How to get the KML data from a GGeoXml object

I load an KML file into a google map object using the following code:

map = new GMap2(document.getElementById("map_canvas")); 
geoXml = new GGeoXml(kml);
GEvent.addListener(geoXml, "load", function() {
    geoXml.gotoDefaultViewport(map);
    // I would like to read the KML contents here
});
map.addOverlay(geoXml);
// ...

I would like to read the placemarks from the KML file and display them in a list. I know that the information I need is being transferred to the browser but I don't know how to access it.

Solution

  • You can't access it through the API, but the data is available in obfuscated properties inside GGeoXML object. Looking at it in Firebug, I found that information here: geoxml.$q.ia. Look at it yourself to see the properties you need (name, description, etc.).
