I have a KML file overlay on an embedded Google Map using the GGeoXml object. I'd like to be able to access specific placemarks in the KML file from Javascript (for example to highlight a selected polygon on the map in response to user action). Ideally what I'd like to do is something like this (pseudo-code): geoXml.getPlacemarkByName('Foo').focus(); Unforunately the [Google Maps API](http://code.google.com/apis/maps/documentation/reference.html#GGeoXml) doesn't seem to expose the placemarks or any other internals of the KML overlay. Does anyone have any thoughts as to how I might accomplish this? I don't know anything about how the overlays are implemented internally, but it seems like there might be a hack that would let me do this. I'm also using jQuery FWIW.
