title: The ':' character, hexadecimal value 0x3A, cannot be included in a name
body: <p>I have an xml file that contains its element like </p>
  
  <pre><code>&lt;ab:test&gt;Str&lt;/ab:test&gt;  
  </code></pre>
  
  <p>When I am trying to access it using the code:</p>
  
  <pre><code>XElement tempElement = doc.Descendants(XName.Get("ab:test")).FirstOrDefault();
  </code></pre>
  
  <p>It's giving me this error:</p>
  
  <blockquote>
    <p>System.Web.Services.Protocols.SoapException: Server was unable to process request. ---> System.Xml.XmlException: The ':' character, hexadecimal value 0x3A, cannot be included in a name.</p>
  </blockquote>
  
  <p>How should I access it?</p>
