Overwrite XML data Using AS3

Question

I have a file called temp.xml saved out on localhost (I'm running wamp for testing), and it has this in it:

<?xml version="1.0" encoding="utf-8"?>
<1>
<SAVEDATA pos="1"/>
</1>

The idea is, that as you get to checkpoints pos="" would be updated. I can't seem to figure out how to actually edit this. The reason SAVEDATA is within <1> is because I also wanted it to somehow assign a unique ID to each player (There's a login system), and when you login, it checks your ID, and continues the game from where you left off.

if you use the xml like i showed, you can use the following to load and edit the pos attribute:

// load it

var urlLoader:URLLoader = new URLLoader();

urlLoader.addEventListener(Event.COMPLETE,f);

urlLoader.load(new URLRequest("test2.xml"));

var xml:XML;

function f(e:Event):void{

xml = XML(e.target.data);

}

// edit xml: (for example to change player with id="3" to have pos="7", use editXMLF(3,7);

// you don't need to change any code above or below except the parameters you pass when you call editXMLF

function editXMLF(playerID:int, newPOS:int):void{

xml.player.(@id==playerID.toString()).SAVEDATA.@pos = newPOS;

}

do you want to add the SAVEDATA node or edit its pos attribute?p.s. that xml should have a wrapper node and you should not use a number for a node name. use something like:
