Process each child of a movie clip?

[Handycam]

I have a movie clip on stage with several other movie clips inside of it.  How do I refer to each child so I might do stuff to it?  I have done it once before by name, but I'd rather not rely on names:

private function setUpHotSpots():void {                // loop through all the hot spots, hide them, and assign event handlers                var i:int;                var numberOfHotSpots:int = hotSpots_mc.numChildren;                for (i = 0; i < numberOfHotSpots; i++) {                     this["hotSpot"+i].alpha=0;                     this["hotSpot"+i].addEventListener("hotSpotClicked", hotSpotClickHandler);                }           }

use:

for(var i:uint=0;i<parentobject.numChildren;i++){

var displayobject:DisplayObject=parentobject.getChildAt(i);

//

}
