title: Open content.xml in a odt-file directly via php
body: <p>Is it possible to open a xml-file in a odt-container (which is a zip-container) directly via php?
  By now I extract the odt-container manually to get the content.xml file out of it. Would be much easier if my php-script could process the odt-file directly.</p>
  
  <pre><code>$reader = new XMLReader();
  if (!$reader-&gt;open("content.xml", 'UTF-8')) die("Failed to open 'content.xml'");
  while ($reader-&gt;read()){ 
      // Do further processing
  }
  </code></pre>
  
  <p><strong>Update:</strong>
  <code>$reader-&gt;open('zip://'.$odt_file.'#content.xml')</code></p>
