ActionScript 2.0 :: Storing List Of Clients With Various Children In XML File?

I want to do is to Store a list of, say, clients, with various children in an external XML file. It looks like this:

Code:
<?xml version="1.0" encoding="ISO-8859-1"?>
<mycClients>
<client>this is the name of the client</client>
<descrip> this is the description of the client</descrip>
<clientProjects>
[Code] .....

Anyway...when the user clicks a BUTTON (not a dynamic button, but one I place on the stage) I want to load all the client's projects. When the user clicks another button, I wan tto load all of the client's friends. When the user clicks a third button, I want to load the description of the client. Into a SIMPLE text box. Just a regular old dynamic text box which I have placed on the stage myself. When a new button is clicked, the previous data is replaced with the new data.

Code:
clientArray= new Array();
projectArray = new Array ();
descriptArray = new Array ();
var clientXML:XML = new XML();
objL.ignoreWhite = true;
objXML.onLoad=loadXML;
[Code] .....
I just want to keep this all as simple as possible so that I can learn to do it right.
