<?php
$xml = <<<XML
<?xml version="1.0" encoding="utf-8"?>
<document>
	<item>
		<identifier>4</identifier>
		<name>Blah</name>
	</item>
	<item>
		<identifier>18</identifier>
		<name>Second One</name>

XML;

$dom = new DOMDocument();
$dom->loadXML($xml);
$list = $dom->getElementsByTagName('item');

foreach ($list as $item)
{
	/** @var $item DOMElement */
	echo $item->getElementsByTagName('identifier')->item(0)->nodeValue;
}
