Flash ActionScript, update xml file sample

I use the file (XML_LanguagePicker) from the \Macromedia\Flash 8\Samples and Tutorials\Samples\ActionScript
how can update the data in flash automaticlly , when I chang from .xml file in this sample.

Do you mean that you want the swf to update itself every time you make a change to the xml file? If so, you will have to periodically reload the xml, using setInterval for instance.

can you please write a sample script for this ,note i write this script in
flash

import mx.containers.Window;
var languageXML:XML = new XML();
var masterArray:Array = new Array();
languageXML.ignoreWhite = true;
languageXML.onLoad = function(success) {
var currentLangNode:XMLNode = this.firstChild.firstChild;
var i:Number = 0;
for (var childNode = currentLangNode; childNode != null; childNode =
childNode.nextSibling, i++) {
var j:Number = 0;
masterArray = new Array();
masterArray[0] = childNode.nodeName;
j++;
for (var stringNode:XMLNode = childNode.firstChild; stringNode != null;
stringNode = stringNode.nextSibling, j++) {
masterArray[j] = stringNode.firstChild.nodeValue;
}
}

for (var k=0; k < masterArray.length; k++) {
lang_cb.addItem(masterArray[k][0]);
}

name.name.text = masterArray[0][1];
chat.chat.text = masterArray[0][2];
}

var langListener:Object = new Object();
langListener.change = function (eventObj) {
for (var l=0; l < masterArray.length; l++) {
if (masterArray[l][0] == eventObj.target.value) {
welcome_txt.text = masterArray[l][1];
thanks_txt.text = masterArray[l][2];
break;
}
}
}

lang_cb.addEventListener("change",langListener);
languageXML.load("1.xml");

and I have an xml file 1.xml
