Hi,
as it's written earlier. My way is changing INFO_FORMAT in WMS layer to gml,
next I used code from Lucia so result is here:
info = new OpenLayers.Control.WMSGetFeatureInfo({
url: "http://localhost:8080/geoserver/zk/wms";,
title: 'Identify features by clicking',
queryVisible: true,
layers: '',
eventListeners: {
getfeatureinfo: function(event) {
for (var i = 0; i < event.features.length; i++) {
var feature = event.features[i];
var attributes = feature.attributes;
alert(attributes.zona); }}} //zona is attribute I want
});
map.addControl(info);
info.activate();
If you want one attribute in popup, you will have to try combine it ;)
