I've tried several methods, from Linq to loading the data to an XML document, but i can't seem to be able to return the result that i need.

here's the example XML:

<serv:message xmlns:serv="http://www.webex.com/schemas/2002/06/service" xmlns:com="http://www.webex.com/schemas/2002/06/common" xmlns:event="http://www.webex.com/schemas/2002/06/service/event"><serv:header><serv:response><serv:result>SUCCESS</serv:result><serv:gsbStatus>PRIMARY</serv:gsbStatus></serv:response></serv:header><serv:body><serv:bodyContent xsi:type="event:createEventResponse" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><event:sessionKey>11111111</event:sessionKey><event:guestToken>111111111111111111111</event:guestToken></serv:bodyContent></serv:body></serv:message>

And, here's what i've tried to do:

StreamReader reader = new StreamReader(dataStream);
XmlDocument doc = new XmlDocument();
doc.LoadXml(reader.ReadToEnd());
XmlNamespaceManager ns = new XmlNamespaceManager(doc.NameTable);
XmlNamespaceManager ns2 = new XmlNamespaceManager(doc.NameTable);
XmlNamespaceManager ns3 = new XmlNamespaceManager(doc.NameTable);
ns.AddNamespace("serv", "http://www.webex.com/schemas/2002/06/service");
ns2.AddNamespace("com", "http://www.webex.com/schemas/2002/06/common");
ns3.AddNamespace("event", "http://www.webex.com/schemas/2002/06/service/event");
XmlNode node = doc.SelectSingleNode("result",ns);

Yet, for some reason i cannot ever seem to return the actual result, which should be either 'SUCCESS' or 'FAILURE' based on the actual xml above.

How can i do this?
