実際に私はポップアップの例でGetFeatureInfoにこのコードを使用しています。今はポップアップのフィールドを制限したいと思います。フィールドを制限する方法、またはGetFeatureInfoリクエストで特定のフィールドを取得する方法は？

function load() {
map = new OpenLayers.Map({
div: "map",
maxExtent: new OpenLayers.Bounds(143.834,-43.648,148.479,-39.573)

var political = new OpenLayers.Layer.WMS("State Boundaries",

{'layers': 'topp:tasmania_state_boundaries', transparent: true, format: 'image/gif'},

queryVisible: true,
eventListeners: {
getfeatureinfo: function(event) {
map.addPopup(new OpenLayers.Popup.FramedCloud(
"chicken",
//document.getElementById('get').innerHTML = xmlResponse.attribute.state;
map.getLonLatFromPixel(event.xy),
null,
event.text,
null,
true
));
xmlResponse = new OpenLayers.Format.XML().read(event.text);
document.getElementById('h').innerHTML = xmlResponse.attribute.STATE;
}
}
});
map.addControl(info);
info.activate();
map.addControl(new OpenLayers.Control.LayerSwitcher());
map.zoomToMaxExtent();
}

<body onload="load()">

ここでは、特定のフィールドのみを必要としたり、ポップアップ機能のフィールドを制限したりします。私はそれを初めて知っています。
