code clay that gave me a little start.  It is having issues though.  Here is what I am trying to format by reading in the XML like a HTML file.  It is a whitepages api call that I make and it returns XML data

http://api.whitepages.com/reverse_phone/1.0/?phone=7812332311;api_key=9ec586766bf2c9b0bd5f548a50a0b3e2

I need to somehow read this in and it may change and have more nodes etc.

on whitepages.com there is an XSD file but I have no idea how to use all that.  I can just get the XML response
