How to get all XML-Nodes attribute value?

Here is the xml file

<glossary>
<alphabet id="A">
    <term heading= "Anchor" definition="A mechanical device that prevents a vessel from moving"/>
        <term heading= "Atlas" definition="A collection of maps in book form"/>
    </alphabet>
    <alphabet id="D">
        <term heading= "Delay" definition="Time during which some action is awaited"/>
    </alphabet>
    <alphabet id="R">
        <term heading= "Risk" definition="A source of danger; a possibility of incurring loss or misfortune"/>
        <term heading= "Rotate" definition="Turn on or around an axis or a center"/>
    </alphabet>

</glossary>

fla file:

import fl.controls.List;
import fl.events.ListEvent;
var xmlLoader:URLLoader= new URLLoader();
xmlLoader.load(new URLRequest("datalist.xml"));
xmlLoader.addEventListener(Event.COMPLETE, xmlLoaded);
var xmlData:XML= new XML();
var myArr:Array= new Array();
function xmlLoaded(e:Event):void {
    xmlData= new XML(e.target.data);
    xmlData.ignoreWhitespace = true开发者_开发知识库;
    //trace(xmlData.term.length());
    ParseData(xmlData);
}
function ParseData(dispTerm:XML):void {
    var termList:XMLList = dispTerm.alphabet.term.@heading;
    //trace(termList)
    var meaningList:XMLList = dispTerm.alphabet.term.@definition;
    //trace(meaningList)
    for (var i:int = 0; i < termList.length(); i++) {
        var termElement:XML = termList[i];
        var meaningElement:XML = meaningList[i];
        mytermList.addItem({label:termList[i], data:termList[i]});
        mytermList.addEventListener(ListEvent.ITEM_CLICK, itemclicked);
        //meaningList.definition=dispTerm.alphabet.term.@definition;
        //mymeaningList.addItem({label:meaningList[i], data:meaningList[i]});
    }
}

function itemclicked(evt:ListEvent):void {
    //trace(evt.item.definition.attribute);
    /*for (var i:int = 0; i < termList.length(); i++) {
    mymeaningList.addItem({label:meaningList[i], data:meaningList[i]});
    }*/
}

In this example, heading is showing in list, i want when user click on listitem, related definition will show another list. Is it possible in this fla file? or i have to take another class file?

Yes, it is possible in one FLA file.

Just an event listener to your termList to add the meaning to your meaningList on roll over. Something like this:

termList.addEventListener(ListEvent.ITEM_ROLL_OVER, showDetails);

function showDetails(e:ListEvent):void {
    //code to add item to meaningList
}
