I am trying to parse the contents of http://feeds.feedburner.com/riabiz using XDocument.Parse(string) (because it gets cached in a DB.)

However, it keeps failing with the below stack trace when it tries to resolve some URIs in that XML.

I don't care about validation or any of that XML nonsense, I just want the structure parsed. How can I use XDocument without this URI resolution?

System.ArgumentException: The specified path is not of a legal form (empty).
