XML : Any advantages of PyQt4.QtXml over standard xml library?

I am developing an application in PyQt, and one of its features involves dealing with XML.

I have code from other projects lying around, and they are mostly based on xml.dom.minidom, with which I have some familiarity. But since my application is already "immersed" in PyQt code for lots of things, I considered giving Qt's framework some consideration.

Well, it looks quite interesting, well documented, but somewhat overwhelming, so the question is:

Would there be a good reason to prefer (Py)Qt xml framework over minidom or other native python XML library?

I ask because I would not like to go up the learning curve just to realize it was not actually needed.
