Random Sring

I am trying to pull a random string from my xml into a dynamic text field in Flash. In this example, the first text field should bring in a random fruit (Apple, Pear or Orange). Im stuck as to which way I should randomly do this. This is my code right now in my movieclip:

Code:

---

var my_req:URLRequest=new URLRequest("articleInformation.xml"); //PUT IN YOUR XML SOURCE HERE
var my_loader:URLLoader = new URLLoader();
var my_xml:XML;

my_loader.addEventListener(Event.COMPLETE, xmlLoader);
my_loader.load(my_req);

function xmlLoader(event:Event):void {
    my_xml=new XML(my_loader.data);
   
    setupoutput_txt();
}

function setupoutput_txt():void{
    trace(my_xml.*);
    fruit_txt.text=String(my_xml.items.fruit.*);
    vegetable_txt.text=String(my_xml.boardDesc.*);
    furniture_txt.text=String(my_xml.boardColor.*);
}

---

This is the xml which I am using:

Code:

---

<?xml version="1.0" encoding="utf-8"?>

<list>
        <items>
                <fruit>Apple</fruit>
                <fruit>Pear</fruit>
                <fruit>Orange</fruit>
        </items>
                <boardDesc>blah blah blah</boardDesc>
                <boardColor>red</boardColor>
</list>

---

Code:

---

function getRandomNode(nodes:XMLList):XML {
  return nodes[Math.floor(Math.random() * nodes.length())];
}

---

Here is the final code I used:

Code:

---

var my_req:URLRequest=new URLRequest("articleInformation.xml"); //PUT IN YOUR XML SOURCE HERE
var my_loader:URLLoader = new URLLoader();
var my_xml:XML;

my_loader.addEventListener(Event.COMPLETE, xmlLoader);
my_loader.load(my_req);

function xmlLoader(event:Event):void {
    my_xml=new XML(my_loader.data);
   
    setupoutput_txt();
}

function setupoutput_txt():void{
    trace(my_xml.*);
    fruit_txt.text=String(my_xml.items.fruit[Math.floor(Math.random()* my_xml.items.fruit.length())]);
    vegetable_txt.text=String(my_xml.items.vegetable[Math.floor(Math.random()* my_xml.items.vegetable.length())]);
    furniture_txt.text=String(my_xml.items.furniture[Math.floor(Math.random()* my_xml.items.furniture.length())]);
}
