[fmx2004] ramdom xml files

Well it is quite simple but I don’t know How to do it. I have a quiz in xml and what I want to do it’s to open randomly a quiz from 3 xml… In fact, there is only a place in the script where it talk about the xml :

myData.load(“quiz.xml”);

and that’s at the end of the script on frame 1…
How do I set to randomly chose between different xml files.
