Chris, I think you want to add an event listener to the layer for "featuresadded" something like: wfs.events.register('featuresadded', null, function(features) { for(var i=0, len=features.length; i<len; i++) { // do something with each features[i] feature } }); http://dev.openlayers.org/releases/OpenLayers-2.8/doc/apidocs/files/OpenLaye rs/Layer/Vector-js.html These will already be parsed into OL features so you do not need to parse them just, if you juat want the attributes then: features[i].attributes is a hash array of the attributes http://dev.openlayers.org/releases/OpenLayers-2.8/doc/apidocs/files/OpenLaye rs/Feature/Vector-js.html -Steve _______________________________________________ Users mailing list Users@openlayers.org http://openlayers.org/mailman/listinfo/users
