And the Html code is :

<!DOCTYPE html >
<head>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<meta http-equiv="content-type" content="text/html; charset=UTF-8"/>

function load() {
var map = new google.maps.Map(document.getElementById("map"), {

var infoWindow = new google.maps.InfoWindow;

// Change this depending on the name of your PHP file
downloadUrl("exemple.xml", function(data) {
var xml = data.responseXML;
var markers = xml.documentElement.getElementsByTagName("marker");
for (var i = 0; i < markers.length; i++) {
var name = markers[i].getAttribute("name");
var address = markers[i].getAttribute("address");
var type = markers[i].getAttribute("type");
var point = new google.maps.LatLng(
parseFloat(markers[i].getAttribute("lat")),
parseFloat(markers[i].getAttribute("lng")));
var html = "<b>" + name + "</b> <br/>" + address;
var icon = customIcons[type] || {};
var marker = new google.maps.Marker({
map: map,
position: point,
icon: icon.icon,
shadow: icon.shadow
});
bindInfoWindow(marker, map, infoWindow, html);
}
});
}

function bindInfoWindow(marker, map, infoWindow, html) {
google.maps.event.addListener(marker, 'click', function() {
infoWindow.setContent(html);
infoWindow.open(map, marker);
});
}

function downloadUrl(url, callback) {
var request = window.ActiveXObject ?
new ActiveXObject('Microsoft.XMLHTTP') :
new XMLHttpRequest;

request.onreadystatechange = function() {
if (request.readyState == 4) {
request.onreadystatechange = doNothing;
callback(request, request.status);
}
};

request.open('GET', url, true);
request.send(null);
}

function doNothing() {}

</head>

<body onload="load()">
<div id="map" style="width: 500px; height: 300px"></div>
</body>

</html>

The map is well created but without markers ... Thank you in advance for all you helps .

If you add console logging, can you find out what does your markers array look like? — duncan

Reform your XML to the following example

<?xml version="1.0"?>
<markers>
  <marker>
     <name>Pan Africa Market</name>
     <address>1521 1st Ave, Seattle, WA</address>
     <lat>47.608940</lat>
     <lng>-122.340141</lng>
     <type>"restaurant"<type/>
  </marker>
  <marker>
    <...>Next marker info</...>
  </marker>
</markers>

Google Maps Api uses the XPost XML Format
