[PyQt] QXmlQuery example needed

Tue Jun 22 22:21:24 BST 2010

I have tried right now:

q_str = 'doc("/home/rad/project/qt/manager/uis/logic.xml")/logic/rule
query.setQuery(q_str)

also I have handler like this:

class Handler(QAbstractMessageHandler):
    def handleMessage(self, msg_type, desc, identifier, loc):
        print 'QUERY:', msg_type, desc, identifier, loc

and it responds this time:

QUERY: 3 <html xmlns='http://www.w3.org/1999/xhtml/'><body><p>syntax error,
unexpected &lt;number literal&gt;, expecting )</p></body></html>
PyQt4.QtCore.QUrl(u'http://www.w3.org/2005/xqt-errors#XPST0003')
<PyQt4.QtXmlPatterns.QSourceLocation object at 0x2204120>
