title: How to get session variables from XML files?
body: <p>I have created a session variable through a wizard method like this:
  request.session['cid'] = 1 and i am able to get it from python code by using
  request.session.get('cid').
  Now i want to get the cid variable from an XML file in order to set a domain
  on an window action. Is there any way to do this?</p>
