Impossible to return a value

Hi, I have a function that loads my map from an XML File… Il seems that I can’t return any value from the function when I have a XML object open, if i trace() the array directly from the function, it work nicely…
Here is my LoadMap function

function LoadMap(XMLFile:String) {
xml = new XML();
xml.ignoreWhite = true;
xml.load(XMLFile);
    xml.onLoad = function(flag) {
        if(flag) {
        var MapXML = xml.firstChild;
        var i:Number = 0;
        var mapArray = new Array();
            while(MapXML.childNodes* != undefined) { //We list every row for map
            var j:Number = 0;
            var RowXML = MapXML.childNodes*;
            mapArray* = new Array();
                while(RowXML.childNodes[j] != undefined) {
                var CellXML = RowXML.childNodes[j];
                    mapArray*[j] = CellXML.attributes.type;
                j++;
                }
            i++;
            }
            //trace(mapArray); //return the two dimensionnal map array.
            return (mapArray);
        } else { //Error.
        trace("Impossible de charger " + XMLFile);
        return(false);
        }
    }
}

… and my XML File

<?xml version="1.0" encoding="iso-8859-2"?>
<map name="LightHaven">
    <row>
        <cell type="1" />
        <cell type="1" />
        <cell type="1" />
        <cell type="1" />
        <cell type="1" />
        <cell type="1" />
        <cell type="1" />
        <cell type="1" />
    </row>
    <row>
        <cell type="2" />
        <cell type="2" />
        <cell type="2" />
        <cell type="2" />
        <cell type="2" />
        <cell type="2" />
        <cell type="2" />
        <cell type="2" />
    </row>
</map>

Could you help me to find how to solve this problem ? Because it appear at every function that I put XML Object in…

Thanks!
