Hi Jeff,
You really did it! I was searching for missing libs, version
mismatches and wrong path variables but it was as simple as using
the xml file the way you pointed out.
I can confirm that everything works as expected now. I'd like to
point out though (for the record) that the step of
ogrinfo wfs-request.xm
does not only test the file but also prepares it to be used. I
tested using the file without first using ogrinfo but that did not
succeed.
I still do not understand why this was not needed in Mapserver 6
but anyway the problem is solved.
Thanks so much for putting in all that effort and time to help so
very quickly. I think this list is one of the greatest strength
of Mapserver and I want to thank everybody who is helping here!
Best
Lars

Thanks
for providing the response, which indeed states "only WFS 1.0.0 or
0.0.14".
I just followed the GDAL WFS driver page now, and locally was able
to generate a map image with a VERSION=1.1.0 request, with the
following steps:
- (the following steps are adapted from the GDAL WFS driver page
https://gdal.org/drv_wfs.html )
- create a new file named "wfs-request.xml"
- paste the contents of:
<OGRWFSDataSource>
<URL>http://demo.mapserver.org/cgi-bin/wfs?SERVICE=WFS&VERSION=1.1.0&MAXFEATURES=1000</URL>
</OGRWFSDataSource>
- (notice the escaped "&" as noted on the GDAL WFS driver
page)
- make a copy of that file (copy/paste "wfs-request.xml" ) in case
it is overwritten by this process
- test this file/connection through the commandline:
ogrinfo wfs-request.xml
- you should see a response listing the available layers:
INFO: Open of `wfs-request.xml'
using driver `WFS' successful.
1: continents
2: cities
- now we know the name to use in our MapServer layer "DATA"
parameter, so in this case we will use "continents"
- edit your .map file and point your layer to that wfs-request.xml
in the CONNECTION, and set the correct DATA parameter from the
ogrinfo response above, such as:
LAYER
NAME "continents-test"
TYPE POLYGON
STATUS ON
CONNECTION "wfs-request.xml"
CONNECTIONTYPE OGR
DATA "continents"
PROJECTION
"init=epsg:4326"
END
CLASS
NAME "My Continents"
STYLE
COLOR 255 128 128
OUTLINECOLOR 96 96 96
END
END
END # Layer
- (use my small mapfile for testing: https://pastebin.com/GYrXyc9A
)
- now finally have MapServer generate a map image from that WFS
version 1.1.0 connection, by testing at the commandline:
shp2img -m wfs-110-client.map -o ttt.png -all_debug 5
- a file named 'ttt.png' should be generated of the map image, and
at the commandline the response should end with something like:
msSaveImage(ttt.png) total time: 0.015s
msFreeMap(): freeing map at 00228B70.
freeLayer(): freeing layer at 001F1828.
shp2img total time: 3.013s
*** tested with MS4W 4.0.0 (MapServer 7.4.0-dev, GDAL 2.4.0)
Hope that helps,
-jeff
