Problem with classes

1

Hi all, i’m trying to learn about clases, and i tried to make an easy XML loader, but i gotta a problem with the attributes that doen’t take the value i provide with the att variable. it shows me on the trace statement like undefined, and for example if i change the atrribute instead of being dynamic, to be static, it does work.

Any hint or help would be really appreciated

thanks in advance

class XMLS {
    function XMLS(Path:String, textfield:TextField, att:String, n:Number) {
        var miXML:XML = new XML();
        miXML.ignoreWhite = true;
        miXML.onLoad = function(success:Boolean) {
            if (success) {
                attributesLoader(miXML, textfield, att, n);
            } else {
                trace("error loading XML");
            }
        };
        miXML.load(Path);
    }
    public static function attributesLoader(miXML, textfield, att, n) {
        var main:Array = miXML.firstChild.childNodes;
        var numNodes:Number = main.length;
        for (var a:Number = 0; a<numNodes; a++) {
            if (atributos != "0") {
                trace(main[0].attributes.att);
                
            } else {
               trace("there's no attributes")
            }
        }
    }
}
