I'm trying to add a layer to my QGIS project from this URL: http://quegis.labcd.unipi.it/cgi-bin/qgis_mapserv.fcgi?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetCapabilities
Using a WMS connection, I'm able to open it in jpeg or PNG format, but I don't know how to retrieve the alphanumeric part, i.e. feature attributes, which is the interesting part for me. Am I making a mistake or is it impossible via WMS?
