Local KML and MarkerClusterer

Managing KML files with GGeoXml is easy but you can’t use it when your KML is not reachable by Google: you’d better parse it by hand with GXml.

Using the JavaScript Google Maps API V2, I wrote the following example (whose KML is valid like its XHTML Strict) as a starting point when you need to show markers coming from unreachable KML files, as the ones behind proxies, aggregated with MarkerClusterer.

Thanks to Cristiano for a few little hints here and there. :)
