Hi Luca,
The OGC Filter element is required as the document element for filter
parameter.

Addendum.
I discovered what problem was.
OWSLib generates an URL like this:
http:// ....WFSHOST .../&FILTER=<ogc:PropertyIsLike wildCard="%"
singleChar="_" escapeChar="\"
matchCase="false"><ogc:PropertyName>nome_via</ogc:PropertyName><ogc:Literal>VIA
A%</ogc:Literal></ogc:PropertyIsLike>
but it seems that QGIS Server doesn't like this. We should add
<ogc:Filter> and </ogc:Filter> at start and the end of the FILTER value:
http:// ....WFSHOST .../&FILTER=<ogc:Filter><ogc:PropertyIsLike
wildCard="%" singleChar="_" escapeChar="\"
matchCase="false"><ogc:PropertyName>nome_via</ogc:PropertyName><ogc:Literal>VIA
A%</ogc:Literal></ogc:PropertyIsLike></ogc:Filter>
with the last URL, the WFS query works!

Hello,
I'm trying to make this python 3 code with OwsLib working.
In particular, I'm searching a road with the name starting by "VIA
F.", but QGIS Server returns me a road named VIA MATTEOTTI...
Does QGIS Server support PropertyIsLike in WFS?
#!/usr/bim/python3
from owslib.wfs import WebFeatureService
from owslib.etree import etree
from owslib.fes import PropertyIsEqualTo, PropertyIsLike, BBox
wfs =
WebFeatureService(url='https://cartografia.comunelavis.it/wms/cbase')
filt = PropertyIsLike(propertyname='nome_via', literal='VIA F.%',
wildCard='%', matchCase=False)
filterxml = etree.tostring(filt.toXML()).decode("utf-8")
feature = wfs.getfeature(typename=['Civici'], maxfeatures=1,
filter=filterxml)
gml = etree.parse(feature)
print(etree.tostring(gml))
