Preloading internal-class objects

Dear Kirupa.com community,
Let this be my first post. I’ve been messing around with flash for some years and now I’m building my own personal site. I’m in the end of my development and now I faced some kind of problem.

The problem.
If I wish to make a preloader for my site that loads frame no. 2. The site is loaded and is waiting for the xmls that are on frame no. 2 to load before it shows up. Is there a way to load those xmls before getting to the 2nd frame and store them in the memory?

Is there any function to throw the files I want to library so they can be dynamically loaded before the site loads?
