ActionScript 3.0 :: Project Consists In One XML File With Attributes

I have a project that needs to get a XMLList. The project consists in one XML file with attributes. The attributes are: Image, description (of the image) the product title for the image and the same product title for another menu that choose the products.

I'll show you all how its organized:
Right side: a List of Products.. Each click it loads his respective title, image and description on the left side of stage.
My doubt is: How to control these items. How do I control the array?

When I click Item 1 it goes to item 1 image, title and description on the left side. When I click in Item 2 it removes the last item, put the new Item 2 image, title, description, etc.

Code:
var xmlLoader:URLLoader = new URLLoader();
var meuXML:XML; // vai guardar todo o contedo do XML;
var imageLoader:Loader; // ImageLoader;
xmlLoader.load(new URLRequest("tv.xml"));
xmlLoader.addEventListener(Event.COMPLETE, carregouXML);
[Code] .....
