Passing argument/variable to external swf

I am using a carousel with items in it…when the user clicks an item in the carousel, I want a new swf to load to _level0 and replace the carousel on the stage…the new swf reads an xml…however the xml should be different for every item on the carousel…is there any way to pass the xml file name to the loadMovie command so the new swf can use it?

Please help
