As best as I can figure, you can get a list of the number of markers
in the GGeoXml object by the count of the 'nc' elements. example:
var geoXml = new GGeoXml( url );
GEvent.addListener(geoXml, 'load', function() {
if (geoXml.loadedCorrectly()) {
alert( geoXml.nc.length ); // <== THIS GIVES US THE NUMBER OF
ELEMENTS LOADED.
}
});
Someone could correct me if I'm wrong.
