title: parse KML file with geoxml3 and markerclusterer
body: <p>I'm using geoxml3 and markerclusterer to parse a kml file to a google maps api v3 map. this works so far.  </p>
  
  <p>the kml file stores several information.</p>
  
  <pre><code>&lt;Placemark&gt;
     &lt;name&gt;Manfred Mustermann&lt;/name&gt;
     &lt;description&gt;Manfred Mustermann&lt;/description&gt;
     &lt;Point&gt;
        &lt;coordinates&gt;7.0964850607874,51.781641735074,0&lt;/coordinates&gt;
     &lt;/Point&gt;
     &lt;address&gt;Musterstr. 29 Aachen, 52070 Nordrhein-Westfalen&lt;/address&gt;
     &lt;styleUrl&gt;#0&lt;/styleUrl&gt;
  &lt;/Placemark&gt;
  </code></pre>
  
  <p>It´s working to output the Nodes "name" or "description" but not the "address". If I try to output this with place mark.address, undefined is written in the info window.</p>
  
  <p>My Question is, how can I parse also this address info?</p>
  
  <p>here is my code:</p>
  
  <pre><code>$(document).ready(function(){
  var myOptions = {
        zoom: 3,
        mapTypeId: google.maps.MapTypeId.ROADMAP
      };
  
      var mcOptions = {gridSize: 80, maxZoom: 15};
      markers = [];
  
      var map = new google.maps.Map(document.getElementById("map-canvas"), myOptions);
      markerclusterer  = new MarkerClusterer(map, [], mcOptions);
      var infoWindow = new google.maps.InfoWindow({maxWidth:800});
  
      var myParser = new geoXML3.parser({
      map: map, 
      singleInfoWindow:true,
  
      createMarker:function(placemark){
              var point = new google.maps.LatLng(placemark.point.lat, placemark.point.lng);
              var con = "&lt;pre&gt;" + placemark.description + "&lt;br /&gt;&lt;br /&gt;" + placemark.address + "&lt;/pre&gt;";
              var marker = new google.maps.Marker({position:point});
              markers.push(marker);
  
              google.maps.event.addListener(marker, "click", function(){
                  infoWindow.content = con;
                  infoWindow.open(map, marker);
              });
             markerclusterer.addMarker(marker);
      }
  });
      myParser.parse('dat.kml');
    });
  
    function clickMarker(i){
           google.maps.event.trigger(markers[i], "click");
    }
  </code></pre>
  
  <p>Thanks a lot!</p>
