That's correct :) To understand a bit more the background /why/ we have to query the value of the (first) *child* of <foo> (instead of the <foo> node directly): the XML text "bar" is /also/ considered to be a QDomNode, specifically a http://doc.trolltech.com/4.6/qdomtext.html, whereas the parent node - <foo> - would be a http://doc.trolltech.com/4.6/qdomelement.html (I guess, not sure anymore). So yes, <foo> is the parent of text node "bar".
