How to extract params from swf


I have found a nice flipping book at, but cannot get any answers from their support guys. What I need is to run multiple instances of the flipping book, each calling its own xml file link. Right now it calls the default xml file in the default directory.

My question: is it possible to get a list of all params in the swf? I am sure there should be some var defining the url of the xml file, but do not know how to get it from the swf.

Any ideas?
