[OpenLayers-Users] Incomplete GML feature

[Bart van den Eijnden (OSGIS)]

Hi,

you need to embed your GML geometries in a FeatureCollection for it to work.

Example:

    var shell_start = '<wfs:FeatureCollection
xmlns:wfs="http://www.opengis.net/wfs"><gml:featureMember
xmlns:gml="http://www.opengis.net/gml"><feature:features
xmlns:feature="http://mapserver.gis.umn.edu/mapserver"
fid="221"><feature:geometry>';

    var shell_end =
'</feature:geometry></feature:features></gml:featureMember></wfs:FeatureCollection>';

var gml = shell_start + [your GML] + shell_end;

Best regards,
Bart
