I was given a web address, which generates an XML file, based on criteria. The site is like http://www.sitename.com/search.html?data=<?XML version...... ><Criteria1>SOMTHING</Criteria1><Criteria2>SOMTHING2</Criteria2>....

What ends up in the browser, is the data in XML formating. I need to be able to (using ASP.net) allow a user to search the criteria and view the results in a nice neat format.

I don't know where to start! I know if I have an XML file, I can give it a stylesheet, or XSD, or XSLT, or whatever, and format it that way, but I'm clueless where to start, when the data is from a web address...

Any help, or insight to where I should start will be very helpful!
