PHP version: 5.3.0
PHP Bug Type: DOM XML related
Bug description: XPath namespace prefix conflict
Description:
------------
When processing an XML document with namespaces, an XPath query for a node
with a different namespace but the same namespace prefix fails.
This appears to be a conflict between the XPath namespaces and the
document namespaces. It works if either:
- The prefix in the query is replaced with a prefix that doesn't
exist in the document.
- If the prefix in the query matches the prefix in the document.
This was tested with:
- PHP 5.3 from debian experimental: 5.3.0-3
- libxml2 2.7.3.dfsg-2.1
Reproduce code:
---------------
$doc = new DOMDocument();
$doc->loadXML('<prefix:root xmlns:prefix="urn:a" />');
$xp = new DOMXPath($doc);
$xp->registerNamespace('prefix', 'urn:b');
echo($xp->query('//prefix:root')->length . "\n");
Expected result:
----------------
It should not find the root node, since we ask for a node in a different
prefix. I.e. it should print '0'.
Actual result:
--------------
It finds the root node, i.e. it prints '1'.
