Hi to All,
Thanks a lot for your fast reply. Got lot of new information from Geoserver.
I built styles with regexp in QGIS and saved styles as a SLD-style. And
tried to do it really simple without replacing anything at the SLD-file. It
seems that I have to now find another way to determine my regexp. Obviously
the PropertyIsLike function seems to be the best way to do it, as most of
you recommended.
Any idea of the schedule when these regexp kind of functions will be used
against database in Geoserver?
Cheers
Ville Jussila
