Building a game screen based on XML data

I am trying to position a list of movieClips on the screen using positioning data from an xml document.

I've created 2 movieClips in my library with the Class linkage of box01 and box02.

I have an xml document that describes the x and y coordinates I want to use:


<?xml version="1.0" encoding="iso-8859-1"?>
<data>
<art name="box01" x="50" y="50" />
<art name="box02" x="100" y="100" />
</data>

I am able to parse that xml document in flash and see the data:
trace(xmldata.art[0].@name) displays "box01"

Now I want to loop through the length of my xml "art" elements and build my screen (by calling the movieClips box01 and box02 that are in the library).

But I don't know how to use the name box01, box02 etc from the xml doc to create my instances.

This doesn't work, but more or less like this:

var i:uint;
for (i=0; i < xmldata.art.length(); i++) {
//trace(xmldata.art .@name);
var myMovieClip:[xmldata.art.@name] = new [xmldata.art .@name]();
myMovieClip.x = xmldata.art.@x;
myMovieClip.y = xmldata.art .@y;
addChild(myMovieClip);
}


Its this line that I need the syntax help on:

var myMovieClip:[xmldata.art.@name] = new [xmldata.art .@name]();


I want the name of my instances to be the "name" attribute from my xml doc.

I'm close - could someone please help me figure this out?

Thanks - I'll put my full code below.
