Hi all,

Can someone explain me how to use QXmlQuery. I have simple XML file on the
filesystem and I need to get one piece of it. My code following:

        out = QString()
        query  = QXmlQuery()
        q_str = 'doc("./uis/logic.xml")/logic/rule'

        if not query.isValid():
            print 'not valid'

        if not query.evaluateTo(out):
            print 'not evaluated'

It shows me 'not evaluated' for:

<?xml version="1.0" encoding="UTF-8"?>
<logic name="card_types" version="1.0">
  <rule name="flyer">
  <rule name="test">
      <dialog type="list" name="category"/>
