If you don’t know the absolute path of an element in your xml file the using xpath and ‘//’ acts as a wildcard (similar to ‘..’ in as3 i guess) you can run a loop and return all values for those elements.

Handy for this likes RSS feeds or KML files ect.

<?php

$xml = simplexml_load_file('my.xml');

	foreach ($xml->xpath('//xmlnode')  as $node) {
    	echo "\t node: $node <br />\n";

	}
?>
