Hi,

I recently stumpled upon the possibilty of clustering Markers on a
google map ( 
http://googlegeodevelopers.blogspot.com/2009/04/markerclusterer-solution-to-too-many.html
).

However, I can't seem to figure out how to use the code right.
Currently my data is pulled from a MySQL database and then displayed
as markers on the map. That works fine with the help of GDownloadUrl.

Below is the code suggested for clustering, but I do not know how to
get my data in there.

>From my (probably wrong) point of view I should just have to change
the expression "data.photos[i].latitude" to get the data from my
generated xml file.

I would appreciate any help on how to do this.

Thanks!

Enrique.



  if(GBrowserIsCompatible()) {
    map = new GMap2($('map'));
    map.setCenter(new GLatLng(39.91, 116.38), 2);
    map.addControl(new GLargeMapControl());

    var markers = [];
    for (var i = 0; i < 100; ++i) {
      var latlng = new GLatLng(data.photos[i].latitude,
data.photos[i].longitude);
      var marker = new GMarker(latlng);
      markers.push(marker);
    }
    var markerCluster = new MarkerClusterer(map, markers);
  }
