Description:
------------
DOMNodeList->item(int index) always returns first element in the list.
I tried to cycle over childNodes, using a for cycle: it finds the correct child count, but always gets first item!

I tried on this xml:
<?xml version="1.0"?>
<root><child 
id="1">value 1</child><child 
id="2">value 2</child><child 
id="3">value 3</child><child 
id="4">value 4</child></root>

Reproduce code:
---------------
<pre><?php
	$domdoc = new DOMDocument();
	//$domdoc->
	$domdoc->load("test.xml");
	$domdoc->normalize();
	$root = $domdoc->getElementsByTagName("root")->item(0);
	echo wordwrap(htmlentities($domdoc->saveXML()))."\n------\n";
	$nodeList = $root->childNodes;
	$childrenCount = $nodeList->length;
	echo "\tchildren count: ".$childrenCount."\n";
	for ($i = 0; $i < $childrenCount; $i++)
	{
		$_tmp_node = $nodeList->item($i);
		echo $i."\t";
		echo $_tmp_node->tagName."\t";
		echo $_tmp_node->getAttribute("id")."\t";
		echo $_tmp_node->nodeValue."\n";
	}
?></pre>


Expected result:
----------------
<?xml version="1.0"?>
<root><child id="1">value 1</child><child
id="2">value 2</child><child
id="3">value 3</child><child
id="4">value 4</child></root>

------
	children count: 4
0	child	1	value 1
1	child	2	value 2
2	child	3	value 3
3	child	4	value 4

Actual result:
--------------
<?xml version="1.0"?>
<root><child id="1">value 1</child><child
id="2">value 2</child><child
id="3">value 3</child><child
id="4">value 4</child></root>

------
	children count: 4
0	child	1	value 1
1	child	1	value 1
2	child	1	value 1
3	child	1	value 1
