Problem getting data from xml...

[qrosity]

Why message var is always empty?

var x:XML = new XML();
x.ignoreWhite = true;
var total:Number;
var clave:Array = new Array();
var friends:Array = new Array();
var birthday:Array = new Array();
var favourite:Array = new Array();
var telephone:Array = new Array();
var address:Array = new Array();
var message:String;

x.onLoad = function(success) {
	if (success) {
	var friendsdata:Array = this.firstChild.childNodes;
	total = friendsdata.length;
	for(i=0;i<friendsdata.length;i++) {
		clave.push(friendsdata[i].attributes.clave);
		friends.push(friendsdata[i].attributes.friends);
		birthday.push(friendsdata[i].attributes.birthday);
		favourite.push(friendsdata[i].attributes.favourite);
		telephone.push(friendsdata[i].attributes.telephone);
		address.push(friendsdata[i].attributes.address);
	}
for(m = 0 ; m < total ; m++){
message += _global.count[m]+" "+friends[m]+". ";
		}
	}
}
x.load("power.xml");
trace(message);

THE XML:

<?xml version="1.0" encoding="ISO-8859-1"?>
<speech>
<friendsdata clave="10" birthday="10-09-1987" favourite="potato" telephone="Lorem ipsum dolor sit amet consectetuer adipiscing elit. Donec blandit sapien a mi. Nulla euismod ornare elit.

<friendsdata clave="11" birthday="12-28-1990" favourite="bogus" telephone="Nulla placerat, dolor non tempus fringilla, justo lacus vehicula urna, non scelerisque nibh enim quis est. Maecenas vel enim. Morbi mattis. " />

By the way, I have several questions about XML loaded vars that may a gentle soul in this forum answer for my intelectual pleasure and sanity.

Considering a big XML:

- Should I load all the vars at the beggining of the movie to have them at my dispossal for the whole movie?
- Does this works or will they dissappear next frame?
- Do loaded vars become timeline vars?
- Is it better to load the XML in pieces, just the needed values for every frame?
- If so, do I need to repeat the whole loading operation from scratch?
- Is the lag during loading a real problem? Is there a handy function to prevent the movie to advance till vars are fully loaded?
