Multiple XML files

I could not find any other topics regarding this matter, which I think is somewhat special.

I am constructing a site, and the images and texts will all load through xml files on a server. The thing is that a friend of mine (who is not very good with Flash and Actionscripting, although a good programmer) is constructing a small CMS that generates these xml files.

Now, I’ve managed to load all the dynamic content on one page from ONE xml file. But the CMS developer wants me to load each text field from separate xml files, and he is not compromising no matter how stupid I tell you that idea is.
Now one of my “pages” have got 3 unique text fields. This of course results in loading content from 3 different xml files. I’ve tried everything, but they seem to disturb each other.

Can anyone help me out!?
