Photo Gallery Using XML and Flash- add child?

I have just complete the Photo Gallery tutorial and am trying to modify it as a next step. I have added another child called “header” in the XML file as such:

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
        <caption>Some text.</caption>
        <header>Tomorrow's clean room today.</header>

        <caption>More text.</caption>
        <header>Pick A Color</header>

        <caption>Even More text.</caption>
        <header>See It Now!</header>

I created another dynamic text field and named the instance “header_txt”.

I am trying to create an array of the children here in the actionscript:

xmlNode = this.firstChild;
image = [];
description = [];
header = [];
total = xmlNode.childNodes.length;
for (i=0; i<total; i++) {

image* = xmlNode.childNodes*.childNodes[0].firstChild.nodeValue;
description* = xmlNode.childNodes*.childNodes[1].firstChild.nodeValue;
header* = xmlNode.childnodes*.childNodes[2].firstChild.nodeValue;

I don’t think that last line is correct for getting the headers, how should it be written? I keep getting “undefined” when I test.

Just for more info, here is script that is called when you hit button 1. (I am having 3 buttons, one for each image like a navigation):

function firstImage() {

if (loaded == filesize) {

picture._alpha = 0;
picture.loadMovie(image[0], 1);
desc_txt.text = description[0];
header_txt.text = header[0];


The images and the captions all load fine, but not the header, can anyone tell what I am doing wrong? Thanks
