[GIS] how to remove some fields with the WMSGetFeatureInfo function

Question

I am displaying the attribute data in the popup on clicking on the map using openlayers,geoext.
But i want to hide some fields(fid,…..) from the table in the popup.
How to do this.
Below is my code

var control = new OpenLayers.Control.WMSGetFeatureInfo({
url: "http://localhost:8080/geoserver/cite/wms",
"LAYERS": 'xxxxxx',
srs:'EPSG:3857'
});

        control.events.on({
            getfeatureinfo: function(event) {
                //close existing popup
                if (popup) {
                    popup.destroy();
                }
                popup = new GeoExt.Popup({
                    title: "Feature Info",
                    map: mapPanel.map,
                    lonlat: mapPanel.map.getLonLatFromViewPortPx(event.xy),
                    width: 250,
                    autoScroll: true,
                    collapsible: true,
                    bodyStyle: {padding: 5},
                    location:event.xy,
                    html: event.text
                    });

                popup.show();
                }
        });

 mapPanel.map.addControl(control);
    control.activate();

If you have control over the geoserver and you use the html format, you could modify the template server side. Otherwise I can think of retrieving the FeatureInfo as GML2 or text and modify if client-side. But I don't know how this might be implemented in openlayers.
