GeoXML3 not returning any placemarks

Question

I have a KML file containing some polygons that has been output from an application (not sure which one). When i try to load in the xml, it seems to load fine but doesn't return any placemarks, just an empty array.

Link to KML file

I have simplified the JS just for testing to the following:

var map = new google.maps.Map(document.getElementById('gmap'), {
  center: new google.maps.LatLng(51.503355, -0.127564),
  zoom: 12,
  mapTypeId: google.maps.MapTypeId.ROADMAP
});

var geoxml = new geoXML3.parser({ 
  map : map, 
  singleInfoWindow : false,
  afterParse: useTheData 
});
geoxml.parse('placemarks.kml');

function useTheData(doc) {
  console.log(doc[0].placemarks);
  for (var i = 0; i < doc[0].placemarks.length; i++) {
    console.log( doc[0].placemarks[i].name );
  }
};

When i log the placemarks object i just get [] in the console. Is the file wrong?

I have added the following to my .htaccess

AddType application/vnd.google-earth.kml+xml .kml

And replaced GeoXML.fetchXML with the following (as i was getting "Unable to retreive placemarks.kml")

geoXML3.fetchXML = function (url, callback) {
  function timeoutHandler() {
    callback();
  };
  $.ajax({
      type:       "GET",
      cache:      false,      
      url: url,
      success: function(xml) {
          callback(xml);
      }
  });
};

You need to use geoxml3 from the polys branch or the kmz branch. The trunk is old and doesn't support polygons.
