title: issue to get specific XML element value using C#
body: <p>Suppose I have the following XML document, how to get the element value for a:name (in my sample, the value is Saturday 100)? My confusion is how to deal with the name space. Thanks.</p>
  
  <p>I am using C# and VSTS 2008.</p>
  
  <pre><code>&lt;s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"&gt;

      &lt;PollResponse xmlns="http://tempuri.org/"&gt;
         &lt;PollResult xmlns:a="http://schemas.datacontract.org/2004/07/FOO.WCF" xmlns:i="http://www.w3.org/2001/XMLSchema-instance"&gt;
            &lt;a:name&gt;Saturday 100&lt;/a:name&gt;
         &lt;/PollResult&gt;
      &lt;/PollResponse&gt;
