Hi,

I've got some xml:

var xmlData:XML = 
<1stNode>
    <buttonID>first child node value</buttonID>
    <imageID>second child node value</imageID>
    <labelID>third child node value</labelID>
</1stNode>

Then I want to read specific node value based on a value passed to a function. .

var buttonID = new Button;
var imageID = new Image;
var labelID = new Label;
getNodeValue(buttonID); //the value here is set dynamically
private function getNodeValue (nodeName:String):void {
trace (xmlData.nodeName)                      //doesn't work

var str:String = "xmlData." + nodeName;
var xml:XMLList = str as XMLList             //doesn't work
}

I'm don't know how to get the value when node name is dynamically changed.

use:

getNodeValue(buttonID); //the value here is set dynamically

private function getNodeValue (nodeName:String):void {
trace (xmlData[nodeName])                     
}
