Update Multiple XML files

I have looked a little over the forum but couldn’t find an answer to this right away, I will look if I can find something when I have more time, but incase there isn’t any post like this yet I will ask already.

is there a way to make flash update multiple XML files at the same time?
I have it working for one file and it works fine, but once I try to edit a second file it doesn’t want to update the second file the way it should, all it does is remove everything that was already in that XML file.

thanks for any help in advance, if you need more info of what I need that what I just said, just let me know and I will try to provide more info when I have time.
