[QGIS-Developer] QGIS Server 3.4.7 and WFS Filtering PropertyIsLike

[Luca Manganelli]

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!
