Flash AS3 dynamically added children . Problem with naming them and calling each separated

Question

I need to access each children after i dynamically added them to the stage , but i`m having problems figuring out how .

On click it adds the image to the stage , and I need to make them glow one at a time , with a for() , but I cant figure out how to name them each with its own name ( name + i ) to access them later on .

Thank you in advance

stage.addEventListener(MouseEvent.MOUSE_DOWN, clicky);
var i = 1; 
function clicky(event:MouseEvent):void
{
    i++;
    var fl_MyInstance:LibrarySymbol = new LibrarySymbol();
    addChild(fl_MyInstance);


    var myStageX:Number = Math.round(event.stageX);
    var myStageY:Number = Math.round(event.stageY);

    fl_MyInstance.x = myStageX;
    fl_MyInstance.y = myStageY;

        if(myStageX<150){
            fl_MyInstance.scaleX = fl_MyInstance.scaleY = 1-(myStageX/300);
        }else{
            fl_MyInstance.scaleX = fl_MyInstance.scaleY = 0.5;
            }
}

EDIT: Thank you for your answers . I will try to do it with an array , considering that i want to make them removable later . The point of the project is to create stars across the stage where you click and have a dot move from one star to another making them glow when it hits them .

If you need to access them later by name you could do it by naming the symbols:

...
var fl_MyInstance:LibrarySymbol = new LibrarySymbol();
fl_MyInstance.name = "symbol_" + i;
addChild(fl_MyInstance);
...

I would add them to an Array or Vector instead. That way makes it easy to access them later on. It is also good when disposing them.

...
var fl_MyInstance:LibrarySymbol = new LibrarySymbol();
_symbolList.push(fl_MyInstance)
addChild(fl_MyInstance);
...

+1. The way I do it. Mentioning the use if Vectors got you the up vote. — sberry, Dec 11 '10 at 22:42

You can access them in an array using getChildren. Something like this should work for you:

var children:ArrayCollection = this.getChildren();

foreach(var child:LibrarySymbol in children)
{
...do whatever
}

If you want to access them individually you can use getChild or getChildAt or something similar. Using naming conventions with dynamic data is probably the hardest way to go through it.
