A PAD File Parser

<?php
/*
 This is a simple Demo, on how to parse an PAD File,
 and get the Infos you need. When you use this function
 for your own script, leave credits in it for me.
 This Code is written by Thorsten Sanders from
 http://www.php-coding.org
 To test it, just start the script with,
 http://yourdomain.com/parser.php?file=http://www.padfile.com/pad.xml
 for example, you can read local files as well
