Hi,
I have a class file of LoadXML its not working can anyone help me in that.
ActionScript Code:
package
{
import flash.display.MovieClip;
import fl.transitions.Tween;
import fl.transitions.easing.Strong;
import flash.display.Sprite;
import flash.text.TextField;
import flash.text.TextFormat;
import flash.text.TextFieldAutoSize;
import flash.net.URLLoader;
import flash.net.URLRequest;
import flash.events.Event;
import flash.filters.DropShadowFilter;
public class PieChart extends MovieClip
{
private var piechart:MovieClip = new MovieClip();

private var values:Array = new Array();
private var xmlFile:XML;
private var pie:Number;
private var radiansSoFar:Number = 0;
private var urlLoader:URLLoader = new URLLoader();
private var tween:Tween;
private var format:TextFormat = new TextFormat();
public function PieChart():void
{
/*Text Format*/
format.color = 132744;
format.align = "left";
format.font = "Century Gothic";
format.size = 11;
LoadXML();
buildPieChart(xmlData);
}
private function LoadXML(file:String = "pie.xml"):void
{
urlLoader.load(new URLRequest(file));
urlLoader.addEventListener(Event.COMPLETE, parseXML);
}
private function parseXML(e:Event):void
{
xmlFile = new XML(e.target.data);
//trace(xmlFile);
pie = xmlFile.children().length;
//trace(pie);
buildPieChart(xmlData);
}
private function buildPieChart(xmlData:XML):void
{
var titleList:XMLList = xmlFile.item.title;
var valueList:XMLList = xmlFile.item.value;
for each (var titleElement:XML in titleList)

}
for each (var valueElement:XML in valueList)

}

}
stage.addChild(label);
}
}
}
}
here is the XML file
