I am using the following code to query for a single node, yet my results are
always NULL. Please help, I've tried everything and I am unable to get a
result.

Code:
XmlDocument xml = new XmlDocument();
                xml.LoadXml(strNLETSMessage);

                XmlNamespaceManager nsmgr = new 
XmlNamespaceManager(xml.NameTable);
                nsmgr.AddNamespace("n", "http://www.nlets.org");
