windowXML.onLoad = loadData;
windowXML.load("window.xml");

function loadData() {

titles = [];
image =[];
xpos =[];
ypos =[];
itxt =[];
iimage =[];
ilink =[];
id =[];

for (i=0; i<this.firstChild.childNodes.length; i++) {

titles* = this.firstChild.childNodes*.childNodes[0].firstChild.nodeValue;
image* = this.firstChild.childNodes*.childNodes[1].firstChild.nodeValue;
xpos* = this.firstChild.childNodes*.childNodes[2].firstChild.nodeValue;
ypos* = this.firstChild.childNodes*.childNodes[3].firstChild.nodeValue;

var b = _root.content_clip.inner_clip.ImageHolder.Content.ContentHolder.attachMovie("button", titles*, i);
b._x = xpos*;
b._y = ypos*;
b.txt = titles*;
b.image = image*;

itxt* = this.firstChild.childNodes*.childNodes[4].firstChild.nodeValue;
iimage* = this.firstChild.childNodes*.childNodes[5].firstChild.nodeValue;
ilink* = this.firstChild.childNodes*.childNodes[6].firstChild.nodeValue;
id* = this.firstChild.childNodes*.childNodes[7].firstChild.nodeValue;

var g = _root.attachMovie("infowin", id*, i);
g.infowin.itxt = itxt*;
loadMovie(iimage*,g.infowin.picholder);
g.infowin.ilink = ilink*;

b.onRollOver = function() {
    if (g.infowin._visible == false) { 
        g.infowin._visible = true;
    } else {
        g.infowin._visible = false;
        
    }
};

b.onRollOut = function() {
    if (g.infowin._visible == false) { 
        g.infowin._visible = true;
    } else {
        g.infowin._visible = false;
