It's the one that I have measured to be EXTREMELY slow in Qt 2.x
In fact it's QDomNodeList that's slow.
When you iterate over the result, each time you ask for a position,
it starts from the beginning and iterates to it !

This is fixed in Qt 3, but for the moment, iterating by hand is MUCH faster
than using a QDomNodeList.
