I get selected features when i draw polygon using this
polygonSelectFeatureHighlightControl control.
But i want to export selected features as kml when i draw polygon.
If i write code like this
window.open(wfsProtocol.url+'?service=WFS&srs=EPSG:4326&version='+wfsProtocol.version+'&request=GetFeature&outputFormat=OGR-KML&typeName='+stateLayer.name);
i get kml file for full layer,but i need kml file for selected features when
i draw polygon.
so please reply which param i want add in the window URL(how to form URL) to
download kml file for selected features.
Thanks to all

My code:
//My projection
var projWGS84 = new OpenLayers.Projection("EPSG:4326");
var projSphericalMercator = new OpenLayers.Projection("EPSG:900913");
var wfsProtocol = new OpenLayers.Protocol.WFS({
url: "http://localhost:8080/geoserver/wfs";,
featureType:stateLayer.name,
featureNS:"http://kcubeconsulting.com/geobrowser";,
srsName: "EPSG:4326",
version: "1.0.0"
//outputFormat: "OGR-KML"
});
var selectFeaturevectorLayer = new
OpenLayers.Layer.Vector("selectFeaturevectorLayer");
var vectors=new OpenLayers.Layer.Vector("vectors");
//My control for to highlight selected features when i draw polygon
var polygonSelectFeatureHighlightControl=new
OpenLayers.Control.DrawFeature(
vectors, OpenLayers.Handler.Polygon,{
map:map,
eventListeners: {
"featureadded": function(event) {
featureHighlightWindow.show();
event.feature.geometry.transform(new
OpenLayers.Projection("EPSG:900913"),new
OpenLayers.Projection("EPSG:4326"));
wfsProtocol.read({
filter: new OpenLayers.Filter.Spatial({
type:
OpenLayers.Filter.Spatial.INTERSECTS,
value: event.feature.geometry
}),
callback: function
processSpatialQuery(response)
{
var feat = response.features;
var myArr = [];
for(var i=0; i<feat.length; ++i)
{
myArr[i] = feat[i].clone();
myArr[i].geometry.transform(projWGS84,projSphericalMercator);
}
if(selectFeaturevectorLayer.features.length)
{
selectFeaturevectorLayer.removeAllFeatures();
}
selectFeaturevectorLayer.addFeatures(myArr);
featureHighlightWindow.hide();
}
});
}
}
});
map.addControl(polygonSelectFeatureHighlightControl);
polygonSelectFeatureHighlightControl.activate();
