title: Get returnvalue in xmlcomment
body: <p>As a part of StyleCop, I am examining method-documentation. See the following: </p>
  
  <pre><code>/// &lt;summary&gt;
  /// Copies the node.
  /// &lt;/summary&gt;
  /// &lt;param name="fileName"&gt;Name of the file.&lt;/param&gt;
  /// &lt;param name="originalClassName"&gt;Name of the original class.&lt;/param&gt;
  /// &lt;param name="newClassName"&gt;New name of the class.&lt;/param&gt;
  /// &lt;param name="nodeName"&gt;Name of the node.&lt;/param&gt;
  /// &lt;param name="ID"&gt;The identifier.&lt;/param&gt;
  /// &lt;returns&gt;&lt;/returns&gt;
  /// &lt;exception cref="System.ArgumentNullException"&gt;doc&lt;/exception&gt;
  </code></pre>
  
  <p>My goal is to get the returnvalue out of this block.</p>
  
  <p>The text is given to me as an entire string. I tried parsing it into an XDocument to retrieve the return-element, but was not able to because of the lack of a root-element.</p>
  
  <p>Is there any way for me to retrieve the return-value stored inside <code>&lt;returns&gt;&lt;/returns&gt;</code> tag? (Note that it is empty here by design, because that is actually what I want to discover; if it is empty.</p>
