Preloading XML/HTML

Allright, here’s something for you die-hard coders…

I’m able to make a .swf with a textfield that dynamically loads html files by using xml.
It has buttons so you can change the contents of the textfield with a different html-page.

This works fine, but it looks kinda static…

If seen a tutorial which preloads external .swf’s and has an animation, but does anyone know if this is possible with external html’s? Because you can’t use the bytesloaded function for html pages.

The tutorial is here: http://www.kirupa.com/developer/mx/preloader_transition.htm
