-Status: Open

Type: Bug
Package: DOM XML related
Operating System: *
PHP Version: 5.6.9

Unfortunately this looks like a bug with libxml and not with PHP: Python
import libxml2
doc = libxml2.parseFile("69712.xml")
ctxt = doc.xpathNewContext()
res = ctxt.xpathEval("//node()[namespace::ns]")
print "Found %d nodes\n" % len(res)
finds 3 nodes as well.
Take a look through their tracker[1] to see if there's a bug report for it already (I
didn't see one) and if not please make one. This may also be a symptom of libxml's general
problem with namespaces (eg, [2]).

Description:
------------
A simple XPath that matches namespaces should return all nodes, however, it only returns every
second one.
Using the below link I confirmed this issue for all versions of PHP 5.0.0 - 5.6.9
http://3v4l.org/4qZhu
Test script:
---------------
<?php
$doc = new DOMDocument('1.0', 'UTF-8');
$doc->loadXML('<root xmlns:ns="foo" ns:id="1"> <one/>
<two/> <three/> <four/> <five/> </root>');
$finder = new DOMXPath($doc);
$nodes = $finder->query("//node()[namespace::ns]");
foreach ($nodes as $n) {
var_dump($doc->saveXML($n));
}
Expected result:
----------------
string(78) "<root xmlns:ns="foo" ns:id="1"> <one/> <two/>
<three/> <four/> <five/> </root>"
string(6) "<one/>"
string(6) "<two/>"
string(8) "<three/>"
string(7) "<four/>"
string(7) "<five/>"
Actual result:
--------------
string(78) "<root xmlns:ns="foo" ns:id="1"> <one/> <two/>
<three/> <four/> <five/> </root>"
string(6) "<two/>"
string(7) "<four/>"
