[OpenLayers-Users] one attribute from getFeatureInfo

[vrbikdan]

Hi all,
I'm trying to mine only one attribute from getFeatureInfo. This attribute I
need to store in variables and use it somewhere in the code. I tried change
info_format in request to xml and work with it, but without any progress.
Below is code I use:

info = new OpenLayers.Control.WMSGetFeatureInfo({
            url: "http://localhost:8080/geoserver/zk/wms", 
            title: 'Identify features by clicking',
            queryVisible: true,
	    INFO_FORMAT: 'text/html',
	    eventListeners: {
                getfeatureinfo: function(event) {					
                    document.getElementById('get').innerHTML = event.text;
            }}});
map.addControl(info);
info.activate();

This code shows me styled table, but I need only one attribute. I tried to
change code like this:

info = new OpenLayers.Control.WMSGetFeatureInfo({
            url: "http://localhost:8080/geoserver/zk/wms", 
            title: 'Identify features by clicking',
            queryVisible: true,
			INFO_FORMAT: 'text/html',
			eventListeners: {
                getfeatureinfo: function(event) {
			xmlResponse = new OpenLayers.Format.XML().read(event.text);					
                    document.getElementById('get').innerHTML =
xmlResponse.attribute.ZONA_AVON;//ZONA_AVON is my attribute I need to know
            }}});
			map.addControl(info);
			info.activate();

But this writes me "undefined" and thats all. Do you have any suggestions
how to solved this?

Thanks a lot
Dan

P.S. I'm using Geoserver 2.1.3
