Load kml extendeddata into variable with Geoxml3

Question

I understand that Geoxml3 has a built in feature to load kml extendeddata into variables (from its source code - see bellow), but I couldn\'t find the way to access

Answer 1

In the kmz branch version of geoxml3, the extended data is stored in placemark.vars.val

name: "Alvarães"
percentil: "29.8"
total: "1699"

So, this should work:

    var contentString = '
'+
        '
'+placemark.name+'
'+
        'fora da escola: '+placemark.vars.val.total+'
'
        'percentual: '+placemark.vars.val.percentil+
        '
';
    polygonMouseover(placemark.polygon,contentString);
