Updating flash file with xml or txt file

Hello, Sorry if this is a newb quesiton but I can’t seem to get it right. I have looked at the tutorials for lots of other stuff but for some reason Im having trouble with this one.

I have a simple swf file. Its a box that scrolls. I wish to have this file read in the contents of a txt file or xml file and simply list them in swf file the order they appear in the txt or xml file.

Thanks!
