Preloading question!

I’ve created a simple preloader to load a movie. The movie contains data stored in a xml document, and there is a php file too for saving data into the xml from flash, and when the preloader ends only then the xml file starts loading because my preloading script is very simple and i don’t have much experience in actionscript and i’ve already tried some scripts to add to my preloader to load the xml at the same time, so that when the prealoder ends the external data is already loaded, instead of wait the xml to load after

 [Frame 1]
ifFrameLoaded ("end") {
gotoAndPlay ("start");
[Frame 2]
gotoAndPlay ("load");
