Search XDocument using LINQ without knowing the namespace

Question

Is there a way to search an XDocument without knowing the namespace? I have a process that logs all SOAP requests and encrypts the sensitive data. I want to find any elemen

If your XML documents always defines the namespace in the same node (Request node in the two examples given), you can determine it by making a query and seeing what namespace the result has:

XDocument xDoc = XDocument.Load("filename.xml");
//Initial query to get namespace:
var reqNodes = from el in xDoc.Root.Descendants()
               where el.Name.LocalName == "Request"
               select el;
foreach(var reqNode in reqNodes)
{
    XNamespace xns = reqNode.Name.Namespace;
    //Queries making use of namespace:
    var person = from el in reqNode.Elements(xns + "Person")
                 select el;
}
