Adding xml to a flash eff pattern

I'm new to FlashEff and I have no idea how to integrate a flasheff movie with an xml script that will rotate images. Please take a look at this SWF: [www.discretedata.com].

What I'm looking for is to have the images in each movie clip change every cycle. Let's say 4 images for each of the 3 movie clips. The menu tab in the FlashEff panel has options for adding XML, so I'm assuming that's how it would be done. Since I'm not very experienced with XML either, I need to know what the xml would look like (anything like the simple one below?), and how it would referenced in the flash movie and in the flaheff panel, and what action script would be necessary.

Thanks!
John
