QDomElement conversion

Question

I receive a xml stanza, for instance, like the following in my server app:

<iq from='stpeter@jabber.org/roundabout'
   id='v1'
   type='get'>
   <vCard xmlns='vcard-temp'/>
</iq>

e.g enclosed in QDomeElement object in client's side and sent to server. Hence, I'm trying to save the current xml in QDomElement object in text format in database. And when extracted from DB, and convert it to QDomElement? How can I do this?
