title: Convert ODT to single XML file
body: <p>I know that standards define two versions of ODT file:
   - one is a archive of different files, i.e. meta.xml, content.xml etc,
   - second is one big XML file with all the data.
  (I know above from <a href="http://en.wikipedia.org/wiki/OpenDocument_technical_specification#Document_Representation" rel="nofollow">http://en.wikipedia.org/wiki/OpenDocument_technical_specification#Document_Representation</a>)</p>
  
  <p>The latter version is better for processing, but unfortunately is not produced by OpenOffice.</p>
  
  <p>The question is:
  Do you know any filter, converter, or anything what would help me transform ODT file in archive version into single XML file? The best would be a Java class.</p>
