If you want to access a single node you might want to use 
SelectSingleNode instead of Evaluate, that way you get an XPathNavigator 
and can access the Value property e.g.

   XPathNavigator server = 
nav.SelectSingleNode("//location[@office='JAC']/@server");
   if (server != null) // XPath found node
   {
     Console.WriteLine(server.Value);
   }
   else // handle case that no node was found
   {
     //
   }
