Bug description:DOMXPath query registerNodeNS produces unexpected behavior
Description:
------------
registerNodeNS option (default to true) added with php 5.3.3 produces
unexpected behavior and BC issue.
$registerNodeNS = true seems to remove (overwrite) registered namespaces
with DOMXPath::registerNamespace() method,
Similar problem has been reported with #55700
Test script:
---------------
<?php
$dom = new DOMDocument('1.0', 'UTF-8');
$dom->loadXML('
<ns1:tag xmlns:ns1="http://my.com/ns1"; xmlns:ns2="http://my.com/ns2";>
<ns1:tag-2/>
<ns2:extra/>
</ns1:tag>');
$xpath = new DOMXPath($dom);
$xpath->registerNamespace("ns2", "http://my.com/ns1";);
echo $xpath->query("//ns2:tag-2", null, false)->length."\n";
echo $xpath->query("//ns2:tag-2", null, true)->length,"\n";
/*
* registerNodeNS option should skip prefix registration if
* same prefix is already registered with registerNamespace() method.
*/
Expected result:
----------------
