XML menu that launches swf file into movie clip

I am trying to build an XML Driven Drop Down Menu similar to the one detailed in the tutorial in Kirupa.com. The difference is that instead of the menu item taking the user to another website I want it to launch a swf file in a movie clip. Basically, what I’m trying to do is build a training application where the user clicks a button (created from the XML file) and it starts a movie in a movie clip. Seems simple but I haven’t been able to find anything on it. All the tutorials involving XML menus have the buttons launching URL’s. Does anyone know of a tutorial or something that does something like what I’m after? Thank you
