Hi,
 
Works for me with an URL encoded request:

Aihe: [gdal-dev] ERROR 1: Couldn't fetch requested layer when using a 
filter in the ogr2ogr- GetFeature request
 
Hello,

I'm trying to query a free WFS with filter values via ogr2ogr and write 
the results to a GeoJson file. 

If I use the following URL incl. filter:

https://isk.geobasis-bb.de/ows/feldblockkataster_wfs?SERVICE=WFS&VERSION=2.0.0&REQUEST=GetFeature&TYPENAMES=refbb:Feldblock&SRSNAME=EPSG:25833&filter=
<fes:Filter xmlns:fes="http://www.opengis.net/fes/2.0" xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="
http://www.opengis.net/fes/2.0
http://schemas.opengis.net/filter/2.0/filterAll.xsd"> <fes:And> 
<fes:PropertyIsEqualTo> <fes:ValueReference>FLIK</fes:ValueReference> 
<fes:Literal>DEBBLI1873413738</fes:Literal> </fes:PropertyIsEqualTo> 
<fes:PropertyIsEqualTo> 
<fes:ValueReference>FACHL_GUELTIG_AB</fes:ValueReference> 
<fes:Literal>2022-01-01</fes:Literal> </fes:PropertyIsEqualTo> </fes:And> 
</fes:Filter>

get the error message:

ERROR 1: Couldn't fetch requested layer '
http://schemas.opengis.net/filter/2.0/filterAll. xsd> <fes:And> 
<fes:PropertyIsEqualTo> <fes:ValueReference>FLIK</fes:ValueReference> 
<fes:Literal>DEBBLI1873413738</fes:Literal> </fes:PropertyIsEqualTo> <fes: 
PropertyIsEqualTo> 
<fes:ValueReference>FACHL_GUELTIG_AB</fes:ValueReference> 
<fes:Literal>2022-01-01</fes:Literal> </fes:PropertyIsEqualTo> </fes:And> 
</fes:Filter>'!

and no results.

If I submit the GetFeature request directly in the browser, I get the 
expected result (namely exactly 2 features).
Without the filter on the URL, my GetFeature requests also work as 
expected with ogr2ogr.

What am I doing wrong?

Michael
