Hi Ben,
Ah, that makes sense. I'm posting the working curl command and XML
GetFeature request for others who might be searching through the archives.
The following goes in a file called GetFeature.xml (for example):
<wfs:GetFeature service='WFS' version='2.0.0'
xmlns:topp='http://www.openplans.org/topp'
xmlns:fes='http://www.opengis.net/fes/2.0'
xmlns:wfs='http://www.opengis.net/wfs/2.0'
count='500'>
<wfs:Query typeNames='geo:siteLog'>
<fes:Filter>
<fes:PropertyIsEqualTo>
<fes:ValueReference>geo:siteIdentification/geo:fourCharacterID</fes:ValueReference>
<fes:Literal>AAAA</fes:Literal>
</fes:PropertyIsEqualTo>
</fes:Filter>
</wfs:Query>
</wfs:GetFeature>
Use the following shell command to run the query using POST and store the
result in GetFeature_Result.xml:
curl -X POST -H "Content-type: application/gml+xml;version=3.2" -d
@GetFeature.xml http://localhost:8080/geoserver/wfs > GetFeature_Result.xml
