  2. {
  3. 	for(var i:uint = 0; i < parentChild.numChildren;++i)
  4. 	{
  5. 		//check if child is a DisplayObjectContainer, which could hold more children
  6. 		if(parentChild.getChildAt(i) is DisplayObjectContainer) removeAllChildren(DisplayObjectContainer(parentChild.getChildAt(i)));
  7. 		else
  8. 		{
  9. 			//remove and null child of parent
  10. 			var child:DisplayObject = parentChild.getChildAt(i);
  11. 			parentChild.removeChild(child);
  12. 			child = null;
  13. 		}
  14.  
  15. 	}
  16. 	//remove and null parent
  17. 	parentChild.parent.removeChild(parentChild);
  18. 	parentChild = null;
