Linq To Xml Search XML without knowing the exact structure

How would I parse the following to get the sql message .Net SqlClient Data Provider?

I'm trying to do it with Linq to xml but I'm not having much luck. The xml is recursive so I cant be certain what level the message will appear at

Any ideas?

Thanks

var doc = XDocument.Parse(xml);

XNamespace ns = "http://www.microsoft.com/sql/reportingservices";

string message = (from info in doc.Descendants(ns + "MoreInformation")
                  where info.Element(ns + "MoreInformation") == null
                  select (string)info.Element(ns + "Message")).Single();

Take all elements in the whole document with the name MoreInformation, take only those that don't have any more MoreInformation nested inside them. For them, select the message. Finally, make sure there is only one result.
