Help in AS3

programming flash
1

I am new to AS3 and I have a requirement to load data from XML to different Arrays and display data to stage when user clicks on Buttons present on stage.

I am able to successfully trace the values from .as file. But I need to display this data only on button click (button resides in FLA file)

This is the code

package
{
import flash.display.;
import flash.display.Loader;
import flash.events.Event;
import flash.net.URLLoader;
import flash.net.URLRequest;
import flash.xml.*;
import flash.display.Sprite;

public class itinXML extends MovieClip
{
    private var my_array:Array;
    
    public function itinXML()
    {
        my_array=new Array();
        
        this.loadXML();
    }

    private function loadXML():void
    {
        var loader:URLLoader=new URLLoader();
        loader.addEventListener(Event.COMPLETE,completeHandler);
        
        var request:URLRequest=new URLRequest('itinerary.xml');
        try 
        {
            loader.load(request);
        } 
        catch(error:Error) 
        {
            trace('XML Could not be loaded');
        }
    }
           
    private function completeHandler(event:Event):void
    {
        var loader:URLLoader=URLLoader(event.target);
        var result:XML=new XML(loader.data);
        var myXML:XMLDocument=new XMLDocument();
        myXML.ignoreWhite=true;
        myXML.parseXML(result.toXMLString());
        var node:XMLNode=myXML.firstChild;
        var n:int=node.childNodes.length;
        var itinerary_names_array:Array=new Array;
        for(var i:int=0;i<n;i++)
        {
            itinerary_names_array.push(node.childNodes*.attributes['name']);
            var questions_array:Array=new Array();
            var hint_a_array:Array=new Array();
            var hint_b_array:Array=new Array();
            var s:int=node.childNodes*.childNodes.length;
            for(var j:int=0;j<s;j++)
            {
                questions_array.push(node.childNodes*.childNodes[j].attributes['q']);
                hint_a_array.push(node.childNodes*.childNodes[j].attributes['hint_a']);
                hint_b_array.push(node.childNodes*.childNodes[j].attributes['hint_b']);
            }
            my_array.push(questions_array);
            my_array.push(hint_a_array);
        }
        my_array.push(itinerary_names_array);
        
        trace("Itineraries: " + itinerary_names_array[2] +"

");
trace("Question: “+ questions_array[2] +”
");
trace("Hint 1: “+ hint_a_array[2] +”
");
trace("Hint 2: “+ hint_b_array[2] +”
");
}

}

}

In FLA I tried to get the values on Button click with the following code

character1_btn.addEventListener(MouseEvent.CLICK, clickHandler);

function clickHandler(event:MouseEvent):void {
trace("Question: “+ questions_array[2] +”
");
}

But I got the error ‘1046: Type was not found or was not a compile-time constant: MouseEvent.’

*Can someone help?
