Convert QDomElement to QDomDocument and vs

Question

I've QDomElement object and did the following to convert it to QDomDocument.

// element is the QDomElement object 
QString str;
QTextStream stream(&str, QIODevice::WriteOnly);
element.save(stream, 2); // stored the content of QDomElement to stream

QDomDocument doc;
doc.setContent(str.toUtf8()); // converted the QString to QByteArray

But what about the convertion from QDomDocument to QDomElement? By the way, is there any constructive way to convert QDomElement to QDomDocument?

here is the conversion

 QDomDocument doc;
 doc.setContent( <YOUR XML GOES HERE> );
 QDomElement root = doc.documentElement();
