title: regular expression in xml
body: <p>The Eclipse software has a functionality to search for regular expressions.
  I'd like to search for all <code>&lt;version&gt;0.0.1-SNAPSHOT&lt;/version&gt;</code> strings whose xml parent node is not <code>&lt;parent&gt;</code>.</p>
  
  <p>What would be the easiest way to do that ?</p>
