[OpenLayers-Users] hardcoded gml:featureMemeber of WFS layer in openlayers ?

[Bart van den Eijnden (OSGIS)]

Hi,

basically this requires writing your own format, which can extend
OpenLayers.Format.GML.v3.

OpenLayers only supports the GML 3.1.1 Simple Features profile out of the
box:

http://schemas.opengis.net/gml/3.1.1/profiles/gmlsfProfile/1.0.0/gmlsf.xsd

It should not be too hard to write the format. Make sure you add wfsos to
the namespaces array and add a reader function where necessary.

Btw, in your code below you are using the old GML parser.

Best regards,
Bart
