 - SimpleXML - Revision: 314376
 - libxml2 - version: 2.6.26

XML document generated using Word 2007, saving as regular Word file (doxc), then extracting the "word/document.xml" file from the compressed docx file (open w/7-zip, WinZIP, WinRAR, etc.).

I've been developing a docx parser in PHP and have encountered a strange bug. SimpleXML fails to parse the XML due to a URL in the XML document. I get no errors even with libxml_use_internal_errors(true) and libxml_get_errors(). the same documents parses perfectly fine with DOMDocument and also the W3C validator.

I played around with the XML, trying to add/remove elements causing the parse error, and it turned out to be a URL in the <w:document> node.

It is the URL in this line in the w:document tag: xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main"

Remove the URL, keeping xmlns:w="" makes the parse successful.
