WFS client: add ogc: namspace to filter generated by Mapserver

[assefa]

Filter generated by Mapserver does not include the ogc namespace.

reprorted through mapserver list (miloslav.kmet@…)

Hello.

I need to find a solution how to filter ArcGIS wfs service in mapserver WFS client. I read this document: http://mapserver.org/ogc/filter_encoding.html and there is no topic about xml ns prefixes in filter.

It seems, that esri's wfs services need xml namespace ogc: in every filter element.

I tried id with get from browser and this works as expected: <ogc:Filter><ogc:PropertyIsEqualTo><ogc:PropertyName>eia_eia:IDAKCIA</ogc:PropertyName><ogc:Literal>1833</ogc:Literal></ogc:PropertyIsEqualTo></ogc:Filter> ?service=wfs&version=1.1.0&request=getFeature&typename=eia_eia:EIA_Locality&filter=%3Cogc:Filter%3E%3Cogc:PropertyIsEqualTo%3E%3Cogc:PropertyName%3Eeia_eia:IDAKCIA%3C/ogc:PropertyName%3E%3Cogc:Literal%3E1833%3C/ogc:Literal%3E%3C/ogc:PropertyIsEqualTo%3E%3C/ogc:Filter%3E (tinyurlized:  http://tinyurl.com/yanqfry)

But this won't filter anything and gives me all features: <Filter><PropertyIsEqualTo?><PropertyName?>eia_eia:IDAKCIA</PropertyName><Literal>1833</Literal></PropertyIsEqualTo></Filter> ?service=wfs&version=1.1.0&request=getFeature&typename=eia_eia:EIA_Locality&filter=%3CFilter%3E%3CPropertyIsEqualTo%3E%3CPropertyName%3Eeia_eia:IDAKCIA%3C/PropertyName%3E%3CLiteral%3E1833%3C/Literal%3E%3C/PropertyIsEqualTo%3E%3C/Filter%3E (tinyurlized:  http://tinyurl.com/y9t3rld)

I doubt, that I can get some response from Esri on this topic, because of this thread:  http://forums.esri.com/Thread.asp?c=158&f=2276&t=273488 where folks

So the question is - how to add the ogc: namespace prefix into wfs_filter?

This is how I have configured the WFS in my mapfile:

CONNECTIONTYPE WFS CONNECTION

" http://globus.sazp.sk/arcgis/services/eia/eia/mapserver/wfsserver"

"<PropertyIsEqualTo?><PropertyName?>eia_eia:IDAKCIA</PropertyName><Literal>1833</Literal></PropertyIsEqualTo>"

"wfs_maxfeatures" "1000"

END

Thank you.

Miloslav,

Please update/reopen this bug if any problems.

Thanks

[assefa]

add also the name spaces.

Miloslav, would something like this should work? Please take the time to update this bug to confirm or not the fixes since I do not have Arc to test it.

Hi, sorry for a later response, caused by our ESRI supplier. The solution you proposed above won't work for me.

However after some bothering, I got two working XML.

The difference is in the missing <ogc:Filter|BBOX> in <wfs:Query.

Don't hesitate to play with our  WFS service

Thank you!

I am not sure, but I do not believe that the 2 xmls are valid. What schema is used to validate the xml? Mapserver generate wfs 1.0.0 type request and the xml I described earlier in this bug validates against the  http://schemas.opengis.net/wfs/1.0.0/WFS-basic.xsd
