Problems adding polygon data from GML

Hello,

I'm having some issues trying to add a feature to a vector layer from an WFS response. I think that my response it's well formed but I'm not sure. This is what I get from my WFS server:

<?xml version="1.0" encoding="ISO-8859-1"?>

        </ms:msGeometry>
      </ms:RecintosSigpac>
    </gml:featureMember>
</wfs:FeatureCollection>

And I'm adding the feature by this way:

var features = new OpenLayers.Format.GML().read(response.responseText);
hilites.destroyFeatures();
hilites.addFeatures(features);
hilites.setVisibility(true);

where hilites is a Vector Layer.

I'll show you too my GetFeature url:

http://192.168.1.65/cgi-bin/mapserv.exe?map=../htdocs/MFD/ejemplo_wfs.map&SERVICE=WFS&VERSION=1.1.0&REQUEST=GetFeature&TYPENAME=RecintosSigpac&FILTER=%3CFilter%3E%3CPropertyIsEqualTo%3E%3CPropertyName%3EGID%3C/PropertyName%3E%3CLiteral%3E193303%3C/Literal%3E%3C/PropertyIsEqualTo%3E%3C/Filter%3E

Can someone help me, please?

Thanks.

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:

featureType: "RecintosSigpac",
featureNS: "http://mapserver.gis.umn.edu/mapserver"

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:

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.

Your WFS request has version 1.1.0. That implies that you receive GML v3
output. See this document: [1] for some differences between 1.0 and 1.1.
If you were to specify your request to be 1.0, you would get GML v2 back!

Thanks, at least I have a refutated information. Now I know it, and the next time I hope not to make the same mistake, but I still don't understand why two weeks ago worked, and yesterday it didn't. Anyway, from now on I'll follow the specifications more accuratelly. Thanks.

Un saludo,

Hi!
I can see that the response is gml 3 because of elements like gml:Envelope, gml:posList,…, they belong to gml 3 specification [1].
Concerning your server configuration as I am not a MapServer user I can't answer you, but you can specify the output format in your request url like: '&outputformat=GML2' [2].

[1] http://www.opengeospatial.org/standards/gml
[2] http://www.opengeospatial.org/standards/wfs

Best regards,
Gabriel Nolasco
