Here's a basic example using for each:
<?xml version="1.0"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml";>
<mx:Script><![CDATA[
private var myXML:XML =
<order>
<item id='1' quantity='2'>
<menuName>burger</menuName>
<price>3.95</price>
</item>
<item id='2' quantity='1'>
<menuName>fries</menuName>
<price>1.45</price>
</item>
</order>
private function sumTotal():void {
var t:Number = 0;
for each (var property:XML in myXML.item) {
var q:int = [EMAIL PROTECTED];
var p:Number = property.price;
var total:Number = q * p;
t += total;
}
l1.text = "$" + t.toString();
}
]]></mx:Script>
<mx:Label id="l1"/>
<mx:Button id="b1" click="sumTotal()" label="Get Total"/>
</mx:Application>
