Estoy probando a integar Google Maps con un archivos XMl de direcciones siguiendo un tutorial propio de Google ( http://code.google.com/support/bin/a...22&topic=11369 ).El problema es que al intentar leer el XMl me sale un error "documentElement es nulo o no es un objeto". El codigo que tengo es este:
Código:
El XML tiene este formato:<script type="text/javascript"> //<![CDATA[ var iconBlue = new GIcon(); iconBlue.image = 'http://labs.google.com/ridefinder/images/mm_20_blue.png'; iconBlue.shadow = 'http://labs.google.com/ridefinder/images/mm_20_shadow.png'; iconBlue.iconSize = new GSize(12, 20); iconBlue.shadowSize = new GSize(22, 20); iconBlue.iconAnchor = new GPoint(6, 20); iconBlue.infoWindowAnchor = new GPoint(5, 1); var iconRed = new GIcon(); iconRed.image = 'http://labs.google.com/ridefinder/images/mm_20_red.png'; iconRed.shadow = 'http://labs.google.com/ridefinder/images/mm_20_shadow.png'; iconRed.iconSize = new GSize(12, 20); iconRed.shadowSize = new GSize(22, 20); iconRed.iconAnchor = new GPoint(6, 20); iconRed.infoWindowAnchor = new GPoint(5, 1); var customIcons = []; customIcons["restaurant"] = iconBlue; customIcons["bar"] = iconRed; function load() { if (GBrowserIsCompatible()) { var map = new GMap2(document.getElementById("map")); map.addControl(new GSmallMapControl()); map.addControl(new GMapTypeControl()); map.setCenter(new GLatLng(47.614495, -122.341861), 13); GDownloadUrl("data.xml", function(data) { var xml = GXml.parse(data); var markers = xml.documentElement.getElementsByTagName("marker"); for (var i = 0; i < markers.length; i++) { var name = markers[i].getAttribute("name"); var address = markers[i].getAttribute("address"); var type = markers[i].getAttribute("type"); var point = new GLatLng(parseFloat(markers[i].getAttribute("lat")), parseFloat(markers[i].getAttribute("lng"))); var marker = createMarker(point, name, address, type); map.addOverlay(marker); } }); } } function createMarker(point, name, address, type) { var marker = new GMarker(point, customIcons[type]); var html = "<b>" + name + "</b> <br/>" + address; GEvent.addListener(marker, 'click', function() { marker.openInfoWindowHtml(html); }); return marker; } //]]> </script>
Código:
Alguna idea?<markers> <marker name="Casa" address="" lat="43" lng="-5" type="" /> </markers>
Gracias
