Hi,
instead write you take read:
var geometry_collection = new OpenLayers.Geometry.MultiPoint();
var fts=map.layers[1].features;
for(var i=0;i<fts.length;i++)
geometry_collection.addPoint(fts[i].geometry);
var parser = new OpenLayers.Format.GML();
var feature = new OpenLayers.Feature.Vector();
feature.geometry = geometry_collection;
//features 2 gml
var gml = parser.write(feature);
alert(gml);
//gml 2 feature array
var ftArr = parser.read(gml);
alert(ftArr.length);
alert(ftArr[0].geometry);
map.layers[2].addFeatures(ftArr);Arnd _____ Von: Lucas Heezen - Covadis [mailto:[email protected]] Gesendet: Donnerstag, 1.

This is what I have so far: var geometry_collection = new OpenLayers.Geometry.MultiPoint(); vectorLayer.features.each(function(ff, index) { geometry_collection.addPoint(ff.geometry); }); var writer = new OpenLayers.Format.GML(); var gml = writer.buildGeometry.multipoint(geometry_collection); alert(gml); But is get the following error: this.createElementNS is not a function Met vriendelijke groet, Lucas Heezen Beschrijving: http://www.covadis.nl/emailkop/logo.gif Covadis b.v. t: 026 3616600 Geograaf 12 f: 026 3612317 6921 EW Duiven e: <mailto:[email protected]> [email protected]
