Vista - How to save html page source

Dear all..

I want to save a web page on my disk, but this page is an XML
transformed in HTML. I don't want to save the HTML resulted but the XML
source. I've tried with these lines:

System.Net.WebClient cl = new System.Net.WebClient();

cl.DownloadFile("http://eu.wowarmory.com/character-sheet.xml?r=Hakkar&n=Kaprica",
"C:\\kaprica.XML");

The problem is that the data saved is the HTML transformed and not the
XML source

You can verify accessing my problem access the URL
"http://eu.wowarmory.com/character-sheet.xml?r=Hakkar&n=Kaprica"; your
browser will render it as and HTML page but if you go to the source
you'll noticed this is an XML transformed according to the XSL declared

Thank you very much,

Lorenzo
