You have a scope problem. elements_arr is defined within the onLoad
handler so it won't be accessible from outside (i.e. from your
assignText() function).
You'd better use the static mx.utils.Delegate class to handle the onLoad
event in an easier manner:
import mx.utils.Delegate;
var elements_arr:Array = [];
var aquentDoc:XML = new XML();
aquentDoc.ignoreWhite = true;
aquentDoc.onLoad = Delegate.create(this, this.onAquentDocLoad);
aquentDoc.load("xml url here");
function onAquentDocLoad(success:Boolean):Void {
// ... check for success, XML validation & parsing...
// now fill your array (elements_arr is available)
elements_arr = aquentDoc.firstChild.childNodes;
for (var i = 0; i < elements_arr.length; i++) {
if (elements_arr[i].attributes["id"] != null) {
var headers = elements_arr[i].attributes["id"];
} else {
var content = elements_arr[i];
}
}
// the array is filled, you can call assignText()
assignText();
}
function assignText() {
for (var p in this) {
if (this[p] instanceof TextField) {
trace("found "+this[p]._name);
}
if(this[p]._name == "header01_text"){
this[p].text=elements_arr[i].attributes["id"];
}
}
Hope it helps..

Hi,
An attempt to dynamically assign text gathered from XML nodes has me
stumped. I've the text field instances, but am at a loss how to proceed.
Any help would be appreciated.
Code:
//Create XML Object
var aquentDoc:XML = new XML();
aquentDoc.ignoreWhite = true;
//event handler
aquentDoc.onLoad = function(success:Boolean) {
if (!success) {
trace("Failure Loading aquentDoc XML");
return;
}
//validating the xml file
if (this.status != 0) {
trace("This xmlObject is not well-formed: "+this.status);
return;
}
//Error check - xml data okay!
if (this.firstChild.nodeName.toLowerCase() != "aquentdoc") {
trace("Unexpected XML data: "+this.firstChild.nodeName);
return;
}
//Extract header nodes into an array.
var elements_arr = this.firstChild.childNodes;
for (var i = 0; i<elements_arr.length; i++) {
//trace(elements_arr[i]);
if (elements_arr[i].attributes["id"] != null) {
var headers = elements_arr[i].attributes["id"];
//trace(headers);
} else {
var content = elements_arr[i];
//trace(content);
}
}
};
Code:
//Displays the text fields correctly.
function assignText() {
for (var p in this) {
if (this[p] instanceof TextField) {
//Show each field's name
trace("found "+this[p]._name);
}
}
}
Code:
//Failed attempt at assigning text.
//This should be called from inside the onLoad handler.
function assignText() {
for (var p in this) {
if (this[p] instanceof TextField) {
//Show each field's name
trace("found "+this[p]._name);
}
if(this[p]._name == "header01_text){
this[p].text=elements_arr[i].attributes["id"];
}
