Beginner needs Help.......Multiple XMLs

hi everyone this is my very first post. On browsing this forum it looks very helpful. I am by no means an expert at flash and currently find myself looking at alot of tutorials and e.g’s trying to get my head round what certain actionscript code means.

With it I have been able to create a nifty little xml gallery but the problem i have come across is…

first of all i have three buttons within my fla that when active load different Xml files. It almost works the only thing is that when a button is clicked part of the previous xml file is still visible.

Im pretty sure i need to clear or reset the previously viewed xml data.

…So how do i do this?

help appreciated

thank you.
