#12286 [Fbk->Opn]: xml_parse isn't returning FALSE with malformed <?xml ...?> element

ID: 12286 User updated by: jacek.prucia@7bulls.com Reported By: jacek.prucia@7bulls.com -Status: Feedback +Status: Open Bug Type: XML related Operating System: Debian Potato 2.2 (Linux 2.2.17) PHP Version: 4.0.6 New Comment: just tried expat 1.95.4 (latest from http://expat.sf.net) with: 1. standalone program (expat's outline.c example) 2. php4-STABLE-200208190000 (snaps.php.net) with Apache 1.3.26 compiled with external expat support (--with-expat-dir=/usr) against that fresh 1.95.4 with 1 everything is just fine, parser catches error and displays: Parse error at line 1: unclosed token However i still get the same result with 2, even when manipulating PHP code a bit. In particular -- i have registerd a small function with xml_set_processing_instruction_handler, that just echoes $target and $data to stdout. Same effect -- no error from xml_parse This might be a bit of help -- when I make an ordinary error (with normal tag, not PI) parser catches that out and returns error. Behaviour described in this bug only applies to xml PI tags. I had a quick look at ext/xml/xml.c, but i'm not that familiar with PHP API yet, to be of any help ;) Previous Comments: ------------------------------------------------------------------------ [2002-08-17 03:17:23] chregu@php.net xml_parse has nothing to do with libxml, it uses the expat library. Just as a clarification :) chregu ------------------------------------------------------------------------ [2002-08-17 02:06:55] kalowsky@php.net this actually sounds more like a problem with the library than the PHP code. Have you tried a recent version of the libxml to see if this still continues? While you're at it, do try a newer version of PHP too, although I don't believe the xml extension has changed much. ------------------------------------------------------------------------ [2001-07-20 11:25:17] jacek.prucia@7bulls.com consider XML file beginning with: <?xml version='1.0'?> everything is just fine, but let us have a small typo - lack of question sign at the end like this: <?xml version='1.0'> this isn't correct, but xml_parse() isn't returning FALSE (as it is supposed to do in case of an error). Instead xml_parse() goes on but it isn't able to find any XML element which gives impression of xml_parse() being totally dead... ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=12286&edit=1
