I'm trying to create a menu through XML and i'm using 2
attributes in dat XML one is buttons name and another is link.
This link is not a URL this is a name of another swf which i
wanna load.

xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
var btn_arr = new Array();
var link_arr = new Array();
function loadXML(loaded) {
if (loaded) {
xmlNode = this.firstChild;
total = xmlNode.childNodes.length;
xml_arr = xmlNode.childNodes;
for (i=0; i<total; i++) {
btn_arr.push(xml_arr
.attributes.heading);
link_arr.push(xml_arr.attributes.pageToLoad);
trace('"'+link_arr
+'"');
makeButtons();
function makeButtons() {
for (var i = 0; i<xml_arr.length; i++) {
button0_mc._visible = false;
var btn = button0_mc.duplicateMovieClip("btn"+i+"_mc",
1000+i);
btn._y =
this["btn"+(i-1)+"_mc"]._y+this["btn"+(i-1)+"_mc"]._height+5;
btn._x = 1.1;
btn.button_txt.text = btn_arr;
btn.onRollOver = function() {
trace(bt._name) //always come to btn4_mc
this.effectIn("in");
btn.onRollOut = function() {
this.effectIn("out");
btn.onRelease = function() {
loadMovieNum('"'+link_arr
+'"', i+10); //showing error loading URL
xmlData.load("xml/menu.xml");

Hi,
Well first of all the [i-1] index is giving errors because
when you start with -1 index for XML childNodes that is NULL for
all values anyhow must be giving error for IMAGE only as NULL can
be assigned to STRING. I think you were trying to prevent the last
DUMMY node from loading but the flow was not correct. Second thing
is when you do get to the BARRY node structure your code is having
one typo plus required one addition to fecth the image(see attached
code). So you see it wasn't getting the image path anyhow hence the
errors.
Hope this helps.
Thanks and Regards,
Sumeet
