[mapserver-users] Can Mapserver expressions contain parens?

[Stephen Woodbridge]

Thanks Lars,

I ended up loading the files into postgis and adding new columns and 
populating them then extracting back to a shapefile. I probably could 
have done the same with ogr2ogr.

It just seems like we have basic expressions in mapserver and I had 
forgotten that some tags only take [ATTRIBUTE] and not a full expression.

Cheers,
