How can I read file and put it in to array like a[0] = 22 a[1] = 33 a[4]=11 .... or I should use 2 dimension array ? Is flash AS3.0 has 2 dimension array ?

please help me.

import flash.events.Event;
import flash.net.URLLoader;
import flash.net.URLRequest;

var toLoad:URLRequest = new URLRequest("test.txt");
var loader:URLLoader = new URLLoader(toLoad);
loader.addEventListener(Event.COMPLETE, loaded, false, 0, true);

function loaded(evt:Event):void
{
    var txtData:String = evt.currentTarget.data;
    txtData = txtData.replace(/^\s+/, '');
    txtData = txtData.replace(/\s+/g, ' ');
    txtData = txtData.replace(/\s+$/, '')
    var textAr:Array = txtData.split(" ");
    trace(textAr.toString());
}
