Google Map Markermanager using a xml file

Google Map Markermanager using a xml file

I am trying to adapt this code (comming from Google Developpers)
//<![CDATA[
var map;
var mgr;
var icons = {};
var allmarkers = [];
function load() {
var myOptions = {
zoom: 3,
center: new google.maps.LatLng(50.62504, -100.10742),
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById('map'),
myOptions);
mgr = new MarkerManager(map);
google.maps.event.addListener(mgr, 'loaded', function(){
setupOfficeMarkers();
google.maps.event.addListener(map, 'zoom_changed', function() {
updateStatus(mgr.getMarkerCount(map.getZoom()));
});
});
}
function getIcon(images) {
var icon = false;
if (images) {
if (icons[images[0]]) {
icon = icons[images[0]];
} else {
var iconImage = new google.maps.MarkerImage('images/' +
images[0] + '.png',
new google.maps.Size(iconData[images[0]].width,
iconData[images[0]].height),
new google.maps.Point(0,0),
new google.maps.Point(0, 32));
var iconShadow = new google.maps.MarkerImage('images/' +
images[1] + '.png',
new google.maps.Size(iconData[images[1]].width,
iconData[images[1]].height),
new google.maps.Point(0,0),
new google.maps.Point(0, 32));
var iconShape = {
coord: [1, 1, 1, 32, 32, 32, 32, 1],
type: 'poly'
};
icons[images[0]] = {
icon : iconImage,
shadow: iconShadow,
shape : iconShape
};
}
}
return icon;
}
function setupOfficeMarkers() {
allmarkers.length = 0;
for (var i in officeLayer) {
if (officeLayer.hasOwnProperty(i)) {
var layer = officeLayer[i];
var markers = [];
for (var j in layer["places"]) {
if (layer["places"].hasOwnProperty(j)) {
var place = layer["places"][j];
var icon = getIcon(place["icon"]);
var title = place["name"];
var posn = new google.maps.LatLng(place["posn"][0],
place["posn"][1]);
var marker = createMarker(posn, title,
getIcon(place["icon"]));
markers.push(marker);
allmarkers.push(marker);
}
}
mgr.addMarkers(markers, layer["zoom"][0], layer["zoom"][2]);
}
}
mgr.refresh();
updateStatus(mgr.getMarkerCount(map.getZoom()));
}
function createMarker(posn, title, icon) {
var markerOptions = {
position: posn,
title: title
};
if(icon !== false){
markerOptions.shadow = icon.shadow;
markerOptions.icon = icon.icon;
markerOptions.shape = icon.shape;
}
var marker = new google.maps.Marker(markerOptions);
google.maps.event.addListener(marker, 'dblclick', function() {

updateStatus(mgr.getMarkerCount(map.getZoom()));

google-maps-utility-library-v3 Markermanager
It is an example about how to use markermanager but it is using a js file
as raw material and I would like to use a xml file. I tried several
possibilities but no success.
Here you can find the js file
http://google-maps-utility-library-v3.googlecode.com/svn/trunk/markermanager/examples/google_northamerica_offices.js
The target is to adapt the code in order to use a XML file with these
markers:
Name
icon
Icon_shadow
Long
Lat
Zoom_max
Zoom_min
Some help please !
