Bino, If you access to the feature, for example features[i], you can get the fid by features[i].fid. If you require further information (attributes) there is an array containing that info features[i].attributes.

I solved my problem to. Attached is 2 xml file 1. gml21.xml : This is the original saved from GetFeatureInfo call 2. gml21a.xml : Same as above but manualy rearranged just for human readability factor Curently my parsing fungtion is : //------START Function function setHTML(req) { g = new OpenLayers.Format.GML(); html = "" features = g.read(req.responseText); for(var feat in features) { html += "Feature: Geometry: "+ features[feat].geometry+","; html += "<ul>"; for (var j in features[feat].attributes) { html += "<li>"+j+":"+features[feat].attributes[j]+"</li>"; } html += "</ul>" } document.getElementById('nodeList').innerHTML = html; }; //------STOP Function The current result is : //----START result Feature: Geometry: POINT(110.36599 -7.80068), * label:NGUPASAN * type:0xd00 * level:1 //----STOP result Part of the GML says : //--START GML <gml:featureMember> <spoin:points fid="points.205508"> <gml:boundedBy> <gml:Box srsName="http://www.opengis.net/gml/srs/epsg.xml#4326";> <gml:coordinates xmlns:gml="http://www.opengis.net/gml"; decimal="." cs="," ts=" ">110.36599,-7.80068 110.36599,-7.80068</gml:coordinates> </gml:Box> </gml:boundedBy> <spoin:label>NGUPASAN</spoin:label> <spoin:type>0xd00</spoin:type> <spoin:level>1</spoin:level> <spoin:the_geom> <gml:Point srsName="http://www.opengis.net/gml/srs/epsg.xml#4326";> <gml:coordinates xmlns:gml="http://www.opengis.net/gml"; decimal="." cs="," ts=" ">110.36599,-7.80068</gml:coordinates> </gml:Point> </spoin:the_geom> </spoin:points> </gml:featureMember> //--START GML My Question is : How to extract "FID" from the GML (inside <spoin:points fid="points.205508">) ? Specialy that "205508" number. Sincerely -bino- _______________________________________________ Users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/openlayers-users
