Thanks Andrea, it work now! I have an other problem, maybe you can help me:
I am trying to filter the rows in my vector file such that it matches words 00: or 01: or 02: (and after rows containing 03: or 04: or 05:) I did not find documentation with examples that can help me to correctly write filters like these. Is there a place where you can direct me? Example: My filed "acq_time" in the file vector contains: (acq_time: string type) 00:02 01:13 02:00 03:19 04:22 05:45 I tried various regex and they don't work on my geoserver SLD, but they do work according to this site https://regexr.com/ expression 1: \b(00:|01:|02:)\b expression 2: .*\b(00:|01:|02:)\b.* expression 3: 00:|01:|02: In my SLD: <ogc:Filter> <ogc:PropertyIsEqualTo> <ogc:Function name="strMatches"> <ogc:Literal>acq_time</ogc:Literal> <ogc:Literal>.*\b(00:|01:|02:)\b.*</ogc:Literal> </ogc:Function> <ogc:Literal>true</ogc:Literal> </ogc:PropertyIsEqualTo> </ogc:Filter> Or this: <ogc:Filter> <ogc:PropertyIsEqualTo> <ogc:Function name="strMatches"> <ogc:Literal>acq_time</ogc:Literal> <ogc:Literal>\b(00:|01:|02:)\b</ogc:Literal> </ogc:Function> <ogc:Literal>true</ogc:Literal> </ogc:PropertyIsEqualTo> </ogc:Filter> or this: <ogc:Filter> <ogc:PropertyIsEqualTo> <ogc:Function name="strMatches"> <ogc:Literal>acq_time</ogc:Literal> <ogc:Literal> 01:|02:|03:</ogc:Literal> </ogc:Function> <ogc:Literal>true</ogc:Literal> </ogc:PropertyIsEqualTo> </ogc:Filter> Cheers Pablo El sáb., 10 oct. 2020 a las 4:35, Andrea Aime (<[email protected]>) escribió: > On Sat, Oct 10, 2020 at 4:35 AM Pablo J.
