Hello,
Thank you very much, that piece of code helped me a lot. But I've got a question for you. This 'fucntionallity' worked very well 2 weeks ago, but this week I reviewed it and I realized that it didn't work properly, suddenly the geometries were not selected, and 2 weeks ago they were selected.So I might have made some changes in my WFS server configuration because it worked and now I've had to add this piece of code. My WFS server is defined like this:
MAP

Is there anything here that makes you know that the response of the WFS Service is in GML v3?
How can you specify it in the map file?
The getFeature request I use is this:
http://192.168.1.65/cgi-bin/mapserv.exe?map=../htdocs/MFD/ejemplo_wfs.map&SERVICE=WFS&VERSION=1.1.0&REQUEST=GetFeature&MAXFEATURES=1000&EXCEPTIONS=application/vnd.ogc.se_xml&TYPENAME=RecintosSigpac&FILTER=<Filter><PropertyIsEqualTo><PropertyName>GID</PropertyName><Literal>125</Literal></PropertyIsEqualTo></Filter>
Thanks again.
Un saludo,

Hello David!
The problem is that your get feature output format is gml 3.1.1, so you will have to parse the response with OpenLayers.Format.GML.v3.
To instantiate this class correctly you must specify the feature typeName (without prefix) and the feature namespace, something like:
var format = new OpenLayers.Format.GML.v3({
featureType: "RecintosSigpac",
featureNS: "http://mapserver.gis.umn.edu/mapserver"
});
Best regards,
Gabriel Nolasco
