What you have posted uniquelydrew is an XSL style sheet for a xml file. It is not a xml file as you stated. You have to get the xml file and link that file to this stylesheet.
In the xml file just under this line:
<?xml version="1.0" encoding="ISO-8859-1"?>
Put this line:
<?xml-stylesheet type="text/xsl" href="WRITE THE XSL FILE NAME HERE"?>
