[OpenLayers-Users] ***** SPAM ***** problem to obtain the field value

[bartvde at osgis.nl]

Hi,

you might want to have a look at:

http://trac.openlayers.org/ticket/1812

After applying the patch you can do something like:

function setHTML(response) {
        var format = new OpenLayers.Format.WMSGetFeatureInfo();
        var features = format.read(response.responseXML ||
response.responseText);
}

and you'll get an array of OpenLayers.Feature.Vector which have an
attributes property. See example below how to access that.

But since you are using Geoserver, you can do something like (no need to
apply the patch in this case);

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);
                }
          }
}

* code untested *

Hope this helps.

Best regards,
Bart
