title: regular expression with hash character
body: <p>I'm having trouble recognising a potential hash character.  I am using the following pattern that recognises files of the form: id-1321952010.xml.  Some of these files may contain a # before the id therefore: #id-1321952010.xml need be picked up also.</p>
  
  <p>Presently for the initial case I have:</p>
  
  <pre><code>QRegExp rxLogFileFormat("\\b^[a-zA-Z]+\\-[0-9]{10,10}\\.[xml]{3,3}$\\b");
  </code></pre>
  
  <p>I've tried adding '#?' before the boundary but cannot get it to work correctly, can anyone assist.</p>
