Please do not submit the same bug more than once. An existing bug report already describes this very problem. Even if you feel that your issue is somewhat different, the resolution is likely to be the same. Thank you for your interest in PHP. Dupe of bug #45996 Previous Comments: ------------------------------------------------------------------------ [2009-01-11 09:37:19] tstarling at wikimedia dot org Description: ------------ The xml extension (xml_parser_create() etc) has totally broken entity reference parsing when compiled with a modern libxml2 library. This appears to be due to some clueless code inserted in compat.c 1.37 (November 2004) http://cvs.php.net/viewvc.cgi/php-src/ext/xml/compat.c?r1=1.36&r2=1.37&pathrev=PHP_5_2 parser->parser->wellFormed = 0; parser->wellFormed is set to 1 by libxml's xmlInitParserCtxt(), and then to 0 by all the error cases that make the document not well-formed. Setting wellFormed=0, before parsing even begins, means that all input is unconditionally considered to be not well formed. This probably causes all sorts of bugs, but the present one is an interaction with libxml2 r1177: http://svn.gnome.org/viewvc/libxml2/trunk/parser.c?r1=1176&r2=1177&; At line 5174 on the right, entities such as "<" encountered while wellFormed==0 are ignored. Simply removing the quoted line from compat.c fixes the bug, without breaking any unit tests. Reported to Wikimedia at https://bugzilla.wikimedia.org/show_bug.cgi?id=16554 Reproduce code: --------------- Compile libxml2 from source, version 2.5 or later, and link it to PHP with --with-libxml-dir. <?php function ping($parser, $s) { echo "$s\n"; } $parser = xml_parser_create(); xml_set_character_data_handler($parser,'ping'); xml_parse($parser,'<a>a<b</a>'); ?> Expected result: ---------------- a < b Actual result: -------------- a b ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=47066&edit=1
