To register some of the points I made on IRC:

QXmlStreamReader is stream based; as opposed to DOM based.  That stream based 
approach will not make code more maintainable. It works for small projects, 
not for big ones.
I tried it; its better than SAX, but its not nearly as good as DOM.
next to that; replacing a major part like this is more a KOffice3 thing.
getting koffice end-user-ready is a higher prio; this would do the opposite.
