_______________________________________________________________________________ 2009-10-25 Release 3.64 Gisle Aas (5): Convert files to UTF-8 Don't allow decode_entities() to generate illegal Unicode chars Copyright 2009 Remove rendundant (repeated) test Make parse_file() method use 3-arg open [RT#49434] _______________________________________________________________________________ 2009-10-22 Release 3.63 Gisle Aas (2): Take more care to prepare the char range for encode_entities [RT#50170] decode_entities confused by trailing incomplete entity _______________________________________________________________________________ 2009-08-13 Release 3.62 Ville Skyttä (4): HTTP::Header doc typo fix. Do not bother tracking style or script, they're ignored. Bring HTML 5 head elements up to date with WD-html5-20090423. Improve HeadParser performance. Gisle Aas (1): Doc patch: Make it clearer what the return value from ->parse is _______________________________________________________________________________ 2009-06-20 Release 3.61 Gisle Aas (2): Test that triggers the crash that Chip fixed Complete documented list of literal tags Chip Salzenberg (1): Avoid crash (referenced pend_text instead of skipped_text) Antonio Radici (1): Reference HTML::LinkExttor [RT#43164] _______________________________________________________________________________ 2009-02-09 Release 3.60 Ville Skytta (5): Spelling fixes. Test multi-value headers. Documentation improvements. Do not terminate head parsing on the <object> element (added in HTML 4.0). Add support for HTML 5 <meta charset> and new HEAD elements. Damyan Ivanov (1): Short description of the htextsub example Mike South (1): Suppress warning when encode_entities is called with undef [RT#27567] Zefram (1): HTML::Parser doesn't compile with perl 5.8.0. _______________________________________________________________________________ 2008-11-24 Gisle Aas <gisle@ActiveState.com> Release 3.59 Restore perl-5.6 compatibility for HTML::HeadParser. Improved META.yml _______________________________________________________________________________ 2008-11-17 Gisle Aas <gisle@ActiveState.com> Release 3.58 Suppress "Parsing of undecoded UTF-8 will give garbage" warning with attr_encoded [RT#29089] HTML::HeadParser: - Recognize the Unicode BOM in utf8_mode as well [RT#27522] - Avoid ending up with '/' keys attribute in Link headers. _______________________________________________________________________________ 2008-11-16 Gisle Aas <gisle@ActiveState.com> Release 3.57 The <iframe> element content is now parsed in literal mode. Parsing of <script> and <style> content ends on the first end tag even when that tag was in a quoted string. That seems to be the behaviour of all modern browsers. Implement backquote() attribute as requested by Alex Kapranoff. Test and documentation tweaks from Alex Kapranoff. _______________________________________________________________________________ 2007-01-12 Gisle Aas <gisle@ActiveState.com> Release 3.56 Cloning of parser state for compatibility with threads. Fixed by Bo Lindbergh <blgl@hagernas.com>. Don't require whitespace between declaration tokens. <http://rt.cpan.org/Ticket/Display.html?id=20864> _______________________________________________________________________________ 2006-07-10 Gisle Aas <gisle@ActiveState.com> Release 3.55 Treat <> at the end of document as text. Used to be reported as a comment. Improved Firefox compatibility for bad HTML: - Unclosed <script>, <style> are now treated as empty tags. - Unclosed <textarea>, <xmp> and <plaintext> treat rest as text. - Unclosed <title> closes at next tag. Make <!a'b> a comment by itself. _______________________________________________________________________________ 2006-04-28 Gisle Aas <gisle@ActiveState.com> Release 3.54 Yaakov Belch discovered yet another issue with <script> parsing. Enabling of 'empty_element_tags' got the parser confused if it found such a tag for elements that are normally parsed in literal mode. Of these <script src="..."/> is the only one likely to be found in documents. <http://rt.cpan.org//Ticket/Display.html?id=18965> _______________________________________________________________________________ 2006-04-27 Gisle Aas <gisle@ActiveState.com> Release 3.53 When ignore_element was enabled it got confused if the corresponding tags did not nest properly; the end tag was treated it as if it was a start tag. Found and fixed by Yaakov Belch <code@yaakovnet.net>. <http://rt.cpan.org/Ticket/Display.html?id=18936> _______________________________________________________________________________ 2006-04-26 Gisle Aas <gisle@ActiveState.com> Release 3.52 Make sure the 'start_document' fires exactly once for each document parsed. For earlier releases it did not fire at all for empty documents and could fire multiple times if parse was called with empty chunks. Documentation tweaks and typo fixes. _______________________________________________________________________________ 2006-03-22 Gisle Aas <gisle@ActiveState.com> Release 3.51 Named entities outside the Latin-1 range are now only expanded when properly terminated with ";". This makes HTML::Parser compatible with Firefox/Konqueror/MSIE when it comes to how these entities are expanded in attribute values. Firefox does expand unterminated non-Latin-1 entities in plain text, so here HTML::Parser only stays compatible with Konqueror/MSIE. Fixes <http://rt.cpan.org/Ticket/Display.html?id=17962>. Fixed some documentation typos spotted by <william@knowmad.com>. <http://rt.cpan.org/Ticket/Display.html?id=18062> _______________________________________________________________________________ 2006-02-14 Gisle Aas <gisle@ActiveState.com> Release 3.50 The 3.49 release didn't compile with VC++ because it mixed code and declarations. Fixed by Steve Hay <steve.hay@uk.radan.com>. _______________________________________________________________________________ 2006-02-08 Gisle Aas <gisle@ActiveState.com> Release 3.49 Events could sometimes still fire after a handler has signaled eof. Marked_sections with text ending in square bracket parsed wrong. Fix provided by <paul.bijnens@xplanation.com>. <http://rt.cpan.org/Ticket/Display.html?id=16749> _______________________________________________________________________________ 2005-12-02 Gisle Aas <gisle@ActiveState.com> Release 3.48 Enabling empty_element_tags by default for HTML::TokeParser was a mistake. Reverted that change. <http://rt.cpan.org/Ticket/Display.html?id=16164> When processing a document with "marked_sections => 1", the skipped text missed the first 3 bytes "<![". <http://rt.cpan.org/Ticket/Display.html?id=16207> 2005-11-22 Gisle Aas <gisle@ActiveState.com> Release 3.47 Added empty_element_tags and xml_pic configuration options. These make it possible to enable these XML features without enabling the full XML-mode. The empty_element_tags is enabled by default for HTML::TokeParser. 2005-10-24 Gisle Aas <gisle@ActiveState.com> Release 3.46 Don't try to treat an literal as space. This breaks Unicode parsing. <http://rt.cpan.org/Ticket/Display.html?id=15068> The unbroken_text option is now on by default for HTML::TokeParser. HTML::Entities::encode will now encode "'" by default. Improved report/ignore_tags documentation by Norbert Kiesel <nkiesel@tbdnetworks.com>. Test suite now use Test::More, by Norbert Kiesel <nkiesel@tbdnetworks.com>. Fix HTML::Entities typo spotted by Stefan Funke <bundy@adm.arcor.net>. Faster load time with XSLoader (perl-5.6 or better now required). Fixed POD markup errors in some of the modules. 2005-01-06 Gisle Aas <gisle@ActiveState.com> Release 3.45 Fix stack memory leak caused by missing PUTBACK. Only code that used $p->parse(\&cb) form was affected. Fix provided by Gurusamy Sarathy <gsar@sophos.com>. 2004-12-28 Gisle Aas <gisle@ActiveState.com> Release 3.44 Fix confusion about nested quotes in <script> and <style> text. 2004-12-06 Gisle Aas <gisle@ActiveState.com> Release 3.43 The SvUTF8 flag was not propagated correctly when replacing unterminated entities. Fixed test failure because of missing binmode on Windows. 2004-12-04 Gisle Aas <gisle@ActiveState.com> Release 3.42 Avoid sv_catpvn_utf8_upgrade() as that macro was not available in perl-5.8.0. Patch by Reed Russell <Russell.Reed@acxiom.com>. Add casts to suppress compilation warnings for char/U8 mismatches. HTML::HeadParser will always push new header values. This make sure we never loose old header values. 2004-11-30 Gisle Aas <gisle@ActiveState.com> Release 3.41 Fix unresolved symbol error with perl-5.005. 2004-11-29 Gisle Aas <gisle@ActiveState.com> Release 3.40 Make utf8_mode only available on perl-5.8 or better. It produced garbage with older versions of perl. Emit warning if entities are decoded and something in the first chunk looks like hi-bit UTF-8. Previously this warning was only triggered for documents with BOM. 2004-11-23 Gisle Aas <gisle@ActiveState.com> Release 3.39_92 More documentation of the Unicode issues. Moved around HTML::Parser documentation a bit. New boolean option; $p->utf8_mode to allow parsing of raw UTF-8. Documented that HTML::Entities::decode_entities() can take multiple arguments. Unterminated entities are now decoded in text (compatibility with MSIE misfeature). Document HTML::Entities::_decode_entities(); this variation of the decode_entities() function has been available for a long time, but have not been documented until now. HTML::Entities::_decode_entities() can now be told to try to expand unterminated entities. Simplified Makefile.PL 2004-11-23 Gisle Aas <gisle@ActiveState.com> Release 3.39_91 The HTML::HeadParser will skip Unicode BOM. Previously it would consider the <head> section done when it saw the BOM. The parser will look for Unicode BOM and give appropriate warnings if the form found indicate trouble. If no matching end tag is found for <script>, <style>, <xmp> <title>, <textarea> then generate one where the next tag starts. For <script> and <style> recognize quoted strings and don't consider end element if the corresponding end tag is found inside such a string. 2004-11-17 Gisle Aas <gisle@ActiveState.com> Release 3.39_90 The <title> element is now parsed in literal mode, which means that other tags are not recognized until </title> has been seen. Unicode support for perl-5.8 and better. Decoding Unicode entities always enabled; no longer a compile time option. Propagation of UTF8 state on strings. Patch contributed by John Gardiner Myers <jgmyers@proofpoint.com>. Calculate offsets and lengths in chars for Unicode strings. Fixed link typo in the HTML::TokeParser documentation. 2004-11-11 Gisle Aas <gisle@ActiveState.com> Release 3.38 New boolean option; $p->closing_plaintext Contributed by Alex Kapranoff <alex@kapranoff.ru> 2004-11-10 Gisle Aas <gisle@ActiveState.com> Release 3.37 Improved handling of HTML encoded surrogate pairs and illegally encoded Unicode; <http://rt.cpan.org/Ticket/Display.html?id=7785>. Patch by John Gardiner Myers <jgmyers@proofpoint.com>. Avoid generating bad UTF8 strings when decoding entities representing chars beyond #255 in 8-bit strings. Such bad UTF8 sometimes made perl-5.8.5 and older segfault. Undocument v2 style subclassing in synopsis section. Internal cleanup: Make 'gcc -Wall' happier. Avoid modification of PVs during parsing of attrspec. Another patch by John Gardiner Myers. 2004-04-01 Gisle Aas <gisle@ActiveState.com> Release 3.36 Improved MSIE/Mozilla compatibility. If the same attribute name repeats for a start tag, use the first value instead of the last. Patch by Nick Duffek <html-parser@duffek.com>. <http://rt.cpan.org/Ticket/Display.html?id=5472> 2003-12-12 Gisle Aas <gisle@ActiveState.com> Release 3.35 Documentation fixes by Paul Croome <Paul.Croome@softwareag.com>. Removed redundant dSP. 2003-10-27 Gisle Aas <gisle@ActiveState.com> Release 3.34 Fix segfault that happened when the parse callback caused the stack to get reallocated. The original bug report was <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=217616> 2003-10-14 Gisle Aas <gisle@ActiveState.com> Release 3.33 Perl 5.005 or better is now required. For some reason we get a test failure with perl-5.004 and I don't really feel like debugging that perl any more. Details about this failure can be found at <http://rt.cpan.org/Ticket/Display.html?id=4065>. New HTML::TokeParser method called 'get_phrase'. It returns all current text while ignoring any phrase-level markup. The HTML::TokeParser method 'get_text' now expands skipped non-phrase-level tags as a single space. 2003-10-10 Gisle Aas <gisle@ActiveState.com> Release 3.32 If the document parsed ended with some kind of unterminated markup, then the parser state was not reset properly and this piece of markup would show up in the beginning of the next document parsed. <http://rt.cpan.org/Ticket/Display.html?id=3954> The get_text and get_trimmed_text methods of HTML::TokeParser can now take multiple end tags as argument. Patch by <siegmann@tinbergen.nl> at <http://rt.cpan.org/Ticket/Display.html?id=3166>. Various documentation tweaks. Included another example program: hdump 2003-08-19 Gisle Aas <gisle@ActiveState.com> Release 3.31 The -DDEBUGGING fix in 3.30 was not really there :-( 2003-08-17 Gisle Aas <gisle@ActiveState.com> Release 3.30 The previous release failed to compile on a -DDEBUGGING perl like the one provided by Redhat 9. Got rid of references to perl-5.7. Further fixes to avoid warnings from Visual C. Patch by Steve Hay <steve.hay@uk.radan.com>. 2003-08-14 Gisle Aas <gisle@ActiveState.com> Release 3.29 Setting xml_mode now implies strict_names also for end tags. Avoid warning from Visual C. Patch by <gsar@activestate.com>. 64-bit fix from Doug Larrick <doug@ties.org> http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195500 Try to parse similar to Mozilla/MSIE in certain edge cases. All these are outside of the official definition of HTML but HTML spam often tries to take advantage of these. - New configuration attribute 'strict_end'. Unless enabled we will allow end tags to contain extra words or stuff that look like attributes before the '>'. This means that tags like these: </foo foo="<ignored>"> </foo ignored> </foo ">" ignored> are now all parsed as a 'foo' end tag instead of text. Even if the extra stuff looks like attributes they will not be reported if requested via the 'attr' or 'tokens' argspecs for the 'end' handler. - Parse '</:comment>' and '</ comment>' as comments unless strict_comment is enabled. Previous versions of the parser would report these as text. If these comments contain quoted words prefixed by space or '=' these words can contain '>' without terminating the comment. - Parse '<! "<>" foo>' as comment containing ' "<>" foo'. Previous versions of the parser would terminate the comment at the first '>' and report the rest as text. - Legacy comment mode: Parse with comments terminated with a lone '>' if no '-->' is found before eof. - Incomplete tag at eof is reported as a 'comment' instead of 'text' unless strict_comment is enabled. 2003-04-16 Gisle Aas <gisle@ActiveState.com> Release 3.28 When 'strict_comment' is off (which it is by default) treat anything that matches <!...> a comment. Should now be more efficient on threaded perls. 2003-01-18 Gisle Aas <gisle@ActiveState.com> Release 3.27 Typo fixes to the documentation. HTML::Entities::escape_entities_numeric contributed by Sean M. Burke <sburke@cpan.org>. Included one more example program 'hlc' that show how to downcase all tags in an HTML file. 2002-03-17 Gisle Aas <gisle@ActiveState.com> Release 3.26 Avoid core dump in some cases where the callback croaks. The perl_call_method and perl_call_sv needs G_EVAL flag to be safe. New parser attributes; 'attr_encoded' and 'case_sensitive'. Contributed by Guy Albertelli II <guy@albertelli.com>. HTML::Entities - don't encode \r by default as suggested by Sean M. Burke. HTML::HeadParser - ignore empty http-equiv - allow multiple <link> elements. Patch by Timur I. Bakeyev <timur@gnu.org> Avoid warnings from bleadperl on the uentities test. 2001-05-11 Gisle Aas <gisle@ActiveState.com> Release 3.25 Minor tweaks for build failures on perl5.004_04, perl-5.6.0, and for macro clash under Windows. Improved parsing of <plaintext>... :-) 2001-05-09 Gisle Aas <gisle@ActiveState.com> Release 3.24 $p->parse(CODE) New events: start_document, end_document New argspecs: skipped_text, offset_end The offset/line/column counters was not properly reset after eof. 2001-05-01 Gisle Aas <gisle@ActiveState.com> Release 3.23 If the $p->ignore_elements filter did not work as it should if handlers for start/end events was not registered. 2001-04-17 Gisle Aas <gisle@ActiveState.com> Release 3.22 The <textarea> element is now parsed in literal mode, i.e. no other tags recognized until the </textarea> tag is seen. Unlike other literal elements, the text content is not 'cdata'. The XML ' entity is decoded. It apos-char itself is still encoded as ' as ' is not really an HTML tag, and not recognized by many HTML browsers. 2001-04-10 Gisle Aas <gisle@ActiveState.com> Release 3.21 Fix a memory leak which occurred when using filter methods. Avoid a few compiler warnings (DEC C): - Trailing comma found in enumerator list - "unsigned char" is not compatible with "const char". Doc update. 2001-04-02 Gisle Aas <gisle@ActiveState.com> Release 3.20 Some minor documentation updates. 2001-03-30 Gisle Aas <gisle@ActiveState.com> Release 3.19_94 Implemented 'tag', 'line', 'column' argspecs. HTML::PullParser doc update. eg/hform is an example of HTML::PullParser usage. 2001-03-27 Gisle Aas <gisle@ActiveState.com> Release 3.19_93 Shorten 'report_only_tags' to 'report_tags'. I think it reads better. Bleadperl portability fixes. 2001-03-25 Gisle Aas <gisle@ActiveState.com> Release 3.19_92 HTML::HeadParser made more efficient by using 'ignore_elements'. HTML::LinkExtor made more efficient by using 'report_only_tags'. HTML::TokeParser generalized into HTML::PullParser. HTML::PullParser only support the get_token/unget_token interface of HTML::TokeParser, but is more flexible because the information that make up an token is customisable. HTML::TokeParser is made into an HTML::PullParser subclass. 2001-03-19 Gisle Aas <gisle@ActiveState.com> Release 3.19_91 Array references can be passed to the filter methods. Makes it easier to use them as constructor options. Example programs updated to use filters. Reset ignored_element state on EOF. Documentation updates. The netscape_buggy_comment() method now generates mandatory warning about its deprecation. 2001-03-13 Gisle Aas <gisle@ActiveState.com> Release 3.19_90 This is an developer only release. It contains some new experimental features. The interface to these might still change. Implemented filters to reduce the numbers of callbacks generated: - $p->ignore_tags() - $p->report_only_tags() - $p->ignore_elements() New @attr argspec. Less overhead than 'attr' and allow compatibility with XML::Parser style start events. The whole argspec can be wrapped up in @{...} to signal flattening. Only makes a difference when the target is an array. 2001-03-09 Gisle Aas <gisle@ActiveState.com> Release 3.19 Avoid the entity2char global. That should make the module more thread safe. Patch by Gurusamy Sarathy <gsar@ActiveState.com>. 2001-02-24 Gisle Aas <gisle@ActiveState.com> Release 3.18 There was a C++ style comment left in util.c. Strict C compilers do not like that kind of stuff. 2001-02-23 Gisle Aas <gisle@ActiveState.com> Release 3.17 The 3.16 release broke MULTIPLICITY builds. Fixed. 2001-02-22 Gisle Aas <gisle@ActiveState.com> Release 3.16 The unbroken_text option now works across ignored tags. Fix casting of pointers on some 64 bit platforms. Fix decoding of Unicode entities. Only optionally available for perl-5.7.0 or better. Expose internal decode_entities() function at the Perl level. Reindented some code. 2000-12-26 Gisle Aas <gisle@ActiveState.com> Release 3.15 HTML::TokeParser's get_tag() method now takes multiple tags to match. Hopefully the documentation is also a bit clearer. #define PERL_NO_GET_CONTEXT: Should speed up things for thread enabled versions of perl. Quote some more entities that also happens to be perl keywords. This avoids warnings on perl-5.004. Unicode entities only triggered for perl-5.7.0 or higher. 2000-12-03 Gisle Aas <gisle@ActiveState.com> Release 3.14 If a handler triggered by flushing text at eof called the eof method then infinite recursion occurred. Fixed. Bug discovered by Jonathan Stowe <gellyfish@gellyfish.com>. Allow <!doctype ...> to be parsed as declaration. 2000-09-17 Gisle Aas <gisle@ActiveState.com> Release 3.13 Experimental support for decoding of Unicode entities. 2000-09-14 Gisle Aas <gisle@ActiveState.com> Release 3.12 Some tweaks to get it to compile with "Optimierender Microsoft (R) 32-Bit C/C++-Compiler, Version 12.00.8168, fuer x86." Patch by Matthias Waldorf <matthias.waldorf@zoom.de>. HTML::Entities documentation spelling patch by David Dyck <dcd@tc.fluke.com>. 2000-08-22 Gisle Aas <gisle@ActiveState.com> Release 3.11 HTML::LinkExtor and eg/hrefsub now obtain %linkElements from the HTML::Tagset module. 2000-06-29 Gisle Aas <gisle@ActiveState.com> Release 3.10 Avoid core dump when stack gets relocated as the result of text handler invocation while $p->unbroken_text is enabled. Needed to refresh the stack pointer. 2000-06-28 Gisle Aas <gisle@ActiveState.com> Release 3.09 Avoid core dump if somebody clobbers the aliased $self argument of a handler. HTML::TokeParser documentation update suggested by Paul Makepeace <Paul.Makepeace@realprogrammers.com>. 2000-05-23 Gisle Aas <gisle@ActiveState.com> Release 3.08 Fix core dump for large start tags. Bug spotted by Alexander Fraser <green795@hotmail.com> Added yet another example program: eg/hanchors Typo fix by Jamie McCarthy <jamie@mccarthy.org> 2000-03-20 Gisle Aas <gisle@aas.no> Release 3.07 Fix perl5.004 builds (was broken in 3.06) Declaration parsing mode now only triggers for <!DOCTYPE ...> and <!ENTITY ...>. Based on patch by la mouton <kero@3sheep.com>. 2000-03-06 Gisle Aas <gisle@aas.no> Release 3.06 Multi-threading/MULTIPLICITY compilation fix. Both Doug MacEachern <dougm@pobox.com> and Matthias Urlichs <smurf@noris.net> provided a patch. Avoid some "statement not reached" warnings from picky compilers. Remove final commas in enums as ANSI C does not allow them and some compilers actually care. Patch by James Walden <jamesw@ichips.intel.com> Added eg/htextsub example program. 2000-01-22 Gisle Aas <gisle@aas.no> Release 3.05 Implemented $p->unbroken_text option Don't parse content of certain HTML elements as CDATA when xml_mode is enabled. Offset was reported with wrong sign for text at end of chunk. 2000-01-15 Gisle Aas <gisle@aas.no> Release 3.04 Backed out 3.03-patch that checked for legal handler and attribute names in the HTML::Parser constructor. Documentation typo fixed by Michael. 2000-01-14 Gisle Aas <gisle@aas.no> Release 3.03 We did not get out of comment mode for comments ending with an odd number of "-" before ">". Patch by la mouton <kero@3sheep.com> Documentation patch by Michael. 1999-12-21 Gisle Aas <gisle@aas.no> Release 3.02 Hide ~-magic IV-pointer to 'struct p_state' behind a reference. This allow copying of the internal _hparser_xs_state element, and will make HTML-Tree-0.61 work again. Introduced $p->init() which might be useful for subclasses that only want the initialization part of the constructor. Filled out DIAGNOSTICS section of the HTML::Parser POD. 1999-12-19 Gisle Aas <gisle@aas.no> Release 3.01 Rely on ~-magic instead of a DESTROY method to deallocate the internal 'struct p_state'. This avoid memory leaks when people simply wipe of the content of the object hash. One of the assertion in hparser.c had opposite logic. This made the parser fail when compiled with a -DDEBUGGING perl. Don't assume any specific order of hash keys in the t/cases.t. This test failed with some newer development releases of perl. 1999-12-14 Gisle Aas <gisle@aas.no> Release 3.00 Documentation update (most of it from Michael) Minor patch to eg/hstrip so that it use a "" handler instead of &ignore. Test suite patches from Michael 1999-12-13 Gisle Aas <gisle@aas.no> Release 2.99_96 Patches from Michael: - A handler of "" means that the event will be ignored. More efficient than using 'sub {}' as handler. - Don't use a perl hash for looking up argspec keywords. - Documentation tweaks. 1999-12-09 Gisle Aas <gisle@aas.no> Release 2.99_95 (this is a 3.00 candidate) Fixed core dump when "<" was followed by an 8-bit character. Spotted and test case provided by Doug MacEachern. Doug had been running HTML-Parser-XS through more that 1 million urls that had been downloaded via LWP. Handlers can now invoke $p->eof to request the parsing to terminate. HTML::HeadParser has been simplified by taking advantage of this. Also added a title-extraction example that uses this. Michael once again fixed my bad English in the HTML::Parser documentation. netscape_buggy_comment will carp instead of warn updated TODO/README Documented that HTML::Filter is depreciated. Made backslash reserved in literal argspec strings. Added several new test scripts. 1999-12-08 Gisle Aas <gisle@aas.no> Release 2.99_94 (should almost be a 3.00 candidate) Renamed 'cdata_flag' as 'is_cdata'. Dropped support for wrapping callback handler and argspec in an array and passing a reference to $p->handler. It created ambiguities when you want to pass a array as handler destination and not update argspec. The wrapping for constructor arguments are unchanged. Reworked the documentation after updates from Michael. Simplified internal check_handler(). It should probably simply be inlined in handler() again. Added argspec 'length' and 'undef' Fix statement-less label. Fix suggested by Matthew Langford <langfml@Eng.Auburn.EDU>. Added two more example programs: eg/hstrip and eg/htext. Various minor patches from Michael. 1999-12-07 Gisle Aas <gisle@aas.no> Release 2.99_93 Documentation update $p->bool_attr_value renamed as $p->boolean_attribute_value Internal renaming: attrspec --> argspec Introduced internal 'enum argcode' in hparser.c Added eg/hrefsub 1999-12-05 Gisle Aas <gisle@aas.no> Release 2.99_92 More documentation patches from Michael Renamed 'token1' as 'token0' as suggested by Michael For artificial end tags we now report 'tokens', but not 'tokenpos'. Boolean attribute values show up as (0, 0) in 'tokenpos' now. If $p->bool_attr_value is set it will influence 'tokens' Fix for core dump when parsing <a "> when $p->strict_names(0). Based on fix by Michael. Will av_extend() the tokens/tokenspos arrays. New test suite script by Michael: t/attrspec.t 1999-12-04 Gisle Aas <gisle@aas.no> Release 2.99_91 Implemented attrspec 'offset' Documentation patch from Michael Some more cleanup/updated TODO 1999-12-03 Gisle Aas <gisle@aas.no> Release 2.99_90 (first beta for 3.00) Using "realloc" as a parameter name in grow_tokens created problems for some people. Fix by Paul Schinder <schinder@pobox.com> Patch by Michael that makes array handler destinations really work. Patch by Michael that make HTML::TokeParser use this. This gave a a speedup of about 80%. Patch by Michael that makes t/cases into a real test. Small HTML::Parser documentation patch by Michael. Renamed attrspec 'origtext' to 'text' and 'decoded_text' to 'dtext' Split up Parser.xs. Moved stuff into hparser.c and util.c Dropped html_ prefix from internal parser functions. Renamed internal function html_handle() as report_event(). 1999-12-02 Gisle Aas <gisle@aas.no> Release 2.99_17 HTML::Parser documentation patch from Michael. Fix memory leaks in html_handler() Patch that makes an array legal as handler destination. Also from Michael. The end of marked sections does not eat successive newline any more. The artificial end event for empty tag in xml_mode did not report an empty origtext. New constructor option: 'api_version' 1999-12-01 Gisle Aas <gisle@aas.no> Release 2.99_16 Support "event" in argspec. It expands to the name of the handler (minus "default"). Fix core dump for large start tags. The tokens_grow() routine needed an adjustment. Added test for this; t/largstags.t. 1999-11-30 Gisle Aas <gisle@aas.no> Release 2.99_15 Major restructuring/simplification of callback interface based on initial work by Michael. The main news is that you now need to tell what arguments you want to be provided to your callbacks. The following parser options has been eliminated: $p->decode_text_entities $p->keep_case $p->v2_compat $p->pass_self $p->attr_pos 1999-11-26 Gisle Aas <gisle@aas.no> Release 2.99_14 Documentation update by Michael A. Chase. Fix for declaration parsing by Michael A. Chase. Workaround for perl5.004_05 bug. Can't return &PL_sv_undef. 1999-11-22 Gisle Aas <gisle@aas.no> Release 2.99_13 New Parser.pm POD based on initial work by Michael A. Chase. All new features should now be described. $p->callback(start => undef) will not reset the callback. $p->xml_mode() did not parse attributes correct because HCTYPE_NOT_SPACE_EQ_SLASH_GT flag was never set. A few more tests. 1999-11-18 Gisle Aas <gisle@aas.no> Release 2.99_12 Implemented $p->attr_pos attribute. This causes attr positions within $origtext of the start tag to be reported instead of the attribute values. The positions are reported as 4 numbers; end of previous attr, start of this attr, start of attr value, and end of attr. This should make substr() manipulations of $origtext easy. Implemented $p->unbroken_text attribute. This makes sure that text segments are never broken and given back as separate text callbacks. It delays text callbacks until some other markup has been recognized. More English corrections by Michael A. Chase. HTML::LinkExtor now recognizes even more URI attributes as suggested by Sean M. Burke <sburke@netadventure.net> Completed marked sections support. It is also now a compile time decision if you want this supported or not. The only drawback of enabling it should be a possible parsing speed reduction. I have not measured this yet. The keys for callbacks initialized in the constructor are now suffixed with "_cb". Renamed $p->pass_cbdata to $p->pass_self. Added magic number to the p_state struct. 1999-11-17 Gisle Aas <gisle@aas.no> Release 2.99_11 Don't leak $@ modifications from HTML::Parser constructor. Included HTML::Parser POD. Marked sections almost work. CDATA and RCDATA should work. For tags that take us into literal_mode; <script>, <style>, <xmp>, we did not recognize the end tag unless it was written in all lower case. 1999-11-16 Gisle Aas <gisle@aas.no> Release 2.99_10 The mkhctype and mkpfunc scripts were using \z inside RE. This did not work for perl5.004. Replaced them with plain old dollar signs. 1999-11-15 Gisle Aas <gisle@aas.no> Release 2.99_09 Grammar fixes by Michael A. Chase <mchase@ix.netcom.com> Some more test suite patches for Win32 by Michael A. Chase <mchase@ix.netcom.com> Implemented $p->strict_names attribute. By default we now allow almost anything in tag and attribute names. This is much closer to the behaviour of some popular browsers. This allows us to parse broken tags like this example from the LWP mailing list: <IMG ALIGN=MIDDLE SRC=newprevlstGr.gif ALT=[PREV LIST] BORDER=0> Introduced some tables in "hctype.h" and "pfunc.h". These are built by the corresponding "mk..." script. 1999-11-10 Gisle Aas <gisle@aas.no> Release 2.99_08 Make Parser.xs compile on perl5.004_05 too. New callback called 'default'. This will be called for any document text no other callback shows an interest in. Patch by Michael A. Chase <mchase@ix.netcom.com> that should help clean up files for the test suite on Win32. Can now set up various attributes with key/value pairs passed to the constructor. $p->parse_file() will open the file in binmode() Pass complete processing instruction tag as second argument to process callback. New boolean attribute v2_compat. This influences how attributes are reported for start tags. HTML::Filter now filters process instructions too. Faster HTML::LinkExtor by taking advantage of the new callback interface. The module now also uses URI.pm (instead of the old URI::URL) to absolutize URIs. Faster HTML::TokeParser by taking advantage of new accum interface. 1999-11-09 Gisle Aas <gisle@aas.no> Release 2.99_07 Entities in attribute values are now always expanded. If you set the $p->decode_text_entities to a true value, then you don't have to decode the text yourself. In xml_mode we don't report empty element tags as a start tag with an extra parameter any more. Instead we generate an artificial end tag. 'xml_mode' now implies 'keep_case'. The parser now keeps its own copy of the bool_attr_value value. Avoid memory leak for text callbacks Avoid using ERROR as a goto label. Introduced common internal accessor function for all boolean parser attributes. Tweaks to make Parser.xs compile under perl5.004. 1999-11-08 Gisle Aas <gisle@aas.no> Release 2.99_06 Internal fast decode_entities(). By using it we are able to make the HTML::Entities::decode function 6 times faster than the old one implemented in pure Perl. $p->bool_attr_value() can be set to influence the value that boolean attributes will be assigned. The default is to assign a value identical to the attribute name. Process instructions are reported as "PI" in @accum $p->xml_mode(1) modifies how processing instructions are terminated and allows "/>" at the end of start tags. Turn off optimizations when compiling with gcc on Solaris. Avoids what we believe to be a compiler bug. Should probably figure out which versions of gcc have this bug. 1999-11-05 Gisle Aas <gisle@aas.no> Release 2.99_05 The previous release did not even compile. I forgot to try 'make test' before uploading. 1999-11-05 Gisle Aas <gisle@aas.no> Release 2.99_04 Generalized <XMP>-support to cover all literal parsing. Currently activated for <script>, <style>, <xmp> and <plaintext>. 1999-11-05 Gisle Aas <gisle@aas.no> Release 2.99_03 <XMP>-support. Allow ":" in tag and attribute names Include rest of the HTML::* files from the old HTML::Parser package. This should make testing easier. 1999-11-04 Gisle Aas <gisle@aas.no> Release 2.99_02 Implemented keep_case() option. If this attribute is true, then we don't lowercase tag and attribute names. Implemented accum() that takes an array reference. Tokens are pushed onto this array instead of sent to callbacks. Implemented strict_comment(). 1999-11-03 Gisle Aas <gisle@aas.no> Release 2.99_01 Baseline of XS implementation 1999-11-05 Gisle Aas <gisle@aas.no> Release 2.25 Allow ":" in attribute names as a workaround for Microsoft Excel 2000 which generates such files. Make deprecate warning if netscape_buggy_comment() method is used. The method is used in strict_comment(). Avoid duplication of parse_file() method in HTML::HeadParser. 1999-10-29 Gisle Aas <gisle@aas.no> Release 2.24 $p->parse_file() will not close a handle passed to it any more. If passed a filename that can't be opened it will return undef instead of raising an exception, and strings like "*STDIN" are not treated as globs any more. HTML::LinkExtor knows about background attribute of <tables>. Patch by Clinton Wong <clintdw@netcom.com> HTML::TokeParser will parse large inline strings much faster now. The string holding the document must not be changed during parsing. 1999-06-09 Gisle Aas <gisle@aas.no> Release 2.23 Documentation updates. 1998-12-18 Gisle Aas <aas@sn.no> Release 2.22 Protect HTML::HeadParser from evil $SIG{__DIE__} hooks. 1998-11-13 Gisle Aas <aas@sn.no> Release 2.21 HTML::TokeParser can now parse strings directly and does the right thing if you pass it a GLOB. Based on patch by Sami Itkonen <si@iki.fi>. HTML::Parser now allows space before and after "--" in Netscape comments. Patch by Peter Orbaek <poe@daimi.au.dk>. 1998-07-08 Gisle Aas <aas@sn.no> Release 2.20 Added HTML::TokeParser. Check it out! 1998-07-07 Gisle Aas <aas@sn.no> Release 2.19 Don't end a text chunk with space when we try to avoid breaking up words. 1998-06-22 Gisle Aas <aas@sn.no> Release 2.18 HTML::HeadParser->parse_file will now stop parsing when the <body> starts as it should. HTML::LinkExtor more easily subclassable by introducing the $self->_found_link method. 1998-04-28 Gisle Aas <aas@sn.no> Release 2.17 Never split words (a sequence of non-space) between two invocations of $self->text. This is just a simplification of the code that tried not to break entities. HTML::Parser->parse_file now use smaller chunks as already suggested by the HTML::Parser documentation. 1998-04-02 Gisle Aas <aas@sn.no> Release 2.16 The HTML::Parser could some times break hex entities (like ) in the middle. Removed remaining forced dependencies on libwww-perl modules. It means that all tests should now pass, even if libwww-perl was not installed previously. More tests. 1998-04-01 Gisle Aas <aas@sn.no> Release 2.14, HTML::* modules unbundled from libwww-perl-5.22.
