Preloader/xml/multiple holders

1

I have came across many preloader examples and couldn’t find one that will show how to construct a complex preloader that will calculate and preload multiple images and swfs that xml will load into various holders with different instance name (holder01, holder02, etc) at same time. Below’s a rough preloader I came up for a single holder, so is it possible to adapt the script related to my question? If not, what is another approach I should look into?

this.onEnterFrame = function() {
	holder01._alpha = 0;
	var amount:Number = holder01.getBytesLoaded() / holder01.getBytesTotal() *100;
	loader._xscale = amount;
	percent = int ( (holder.getBytesLoaded()/holder01.getBytesTotal()) * 100 )
         percentage.text = percent;
	if(amount == 100) {
		holder01._alpha = 100;
		loader._visible = false;
		percentage._visible = false;
	}
}
