QXmlStreamReader for parsing XML files

http://doc.qt.nokia.com/4.7-snapshot/qxmlstreamreader.html

 

... and QXmlStreamWriter for writing

http://doc.qt.nokia.com/4.7-snapshot/qxmlstreamwriter.html

 

The Bookmarks reader will be a great example for you :

Re: How to Parse an XML file Using C++ or Cascades

I am just researching parsing XML from local or from remote server right now. lol

 

I found these two links would be helpful to resolve your question:
