Description:
------------
a domxml element has "0" field where its unique id lays. When you call a method, those ids change, below is the code to reproduce this.

I used this XML string:
<?xml version="1.0"?>
<test>
	<row>
		<col>a</col>
		<col>b</col>
		<col>b2</col>
	</row>
	<col>c</col>
	<col>d</col>
</test>

Reproduce code:
---------------
$doc = domxml_open_file('test.xml');

//$element = $doc->first_child();

$xp = $doc->xpath_new_context();
$res = $xp->xpath_eval('//col', $xp);

print_r($res->nodeset);

Expected result:
----------------
comment/uncomment the 3rd line you'll see that ids change

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

The "0" field has nothing to do with an element. Every domxml object has this and its dependant upon when the object was created (calling an additional method returning and object would change the order of object creation).
