Hover captions -that is dynamic captions!

I have a question about Kirupa’s “hover captions” tutorial.

Is there a way to make the content within the rollover effect change dynamically… say with a db of some sort or an XML file? I am not a Flash expert by any means, so I hope this question makes sense.

I have a U.S. map, and we are expecting a few minor changes with some of the items, so we were curious if we can edit the content outside of Flash to make it somewhat easier.

Many thanks!
