title: Parsing section of XML file
body: <p>My xml is like this:</p>
  
  <pre><code>&lt;rootnode&gt;
     &lt;child name="tony"&gt;
     ...
     &lt;/child&gt;
     &lt;child name="antho"&gt;
     ...
     &lt;/child&gt;
  &lt;/rootnode&gt;
  </code></pre>
  
  <p>I want to be able to output the xml element for child tony verbatim. 
  I can find this element using XmlSlurper but then I am left with an object represent, I just want the XML verbatim.  How do I do that?</p>
  
  <pre><code>   &lt;child name="tony"&gt;
     ...
     &lt;/child&gt;
  </code></pre>
