[OpenLayers-Users] Problems to obtain feature value

[fsalas]

Hi, all

I have following problem:

I am trying to obtain the value of a field, but is null

is The variable features.length is zero, how can I resolv this problem?


function setHTML(response) {
        var format = new OpenLayers.Format.GML();
        var features = format.read(response.responseXML || response.responseText);
         for (var i=0, len=features.length; i<len; i++) {
                var feature = features[i];
                for (attribute in feature.attributes) {
                    var value = feature.attributes[attribute];
                    console.log(attribute + ": " + value);
                }
          }
}


   tiled = new OpenLayers.Layer.WMS(
                "topp:cuba - Tiled", "http://deltha:8080/geoserver/wms",
                {
                    width: '800',
                    srs: 'EPSG:4267',
                    layers: 'topp:cuba',
                    height: '300',
                    styles: '',
                    format: 'image/png',
                    tiled: 'true',
                    tilesOrigin : "-86.09241054242432,19.388371083287836"
                },
                {buffer: 0} 
            );


      // support GetFeatureInfo
            map.events.register('click', map, function (e) {
                document.getElementById('nodelist').innerHTML = "Loading... please wait...";
                var url =  map.layers[0].getFullRequestString(
                    {
                        REQUEST: "GetFeatureInfo",
                        EXCEPTIONS: "application/vnd.ogc.se_xml",
                        BBOX: map.getExtent().toBBOX(),
                        X: e.xy.x,
                        Y: e.xy.y,
                        INFO_FORMAT: 'application/vnd.ogc.se_xml',
                        QUERY_LAYERS: map.layers[0].params.LAYERS,
                        FEATURE_COUNT: 50,
                        WIDTH: map.size.w,
                        HEIGHT: map.size.h
                    },
                    "http://deltha:8080/geoserver/wms"
                );
                OpenLayers.loadURL(url, '', this, setHTML, setHTML);
                OpenLayers.Event.stop(e);
            });
