[mapserver-users] Get MAP file CLASSes with no data - empty

[Michal Seidl]

I would like to get in PHP/Python environment the list of CLASSes which do
not target any data. The situation is like this.

1) I am interested only in vector data
2) I have mapfile and running mapserver
3) There is LAYER with many CLASSes which are defined by EXPRESSION in
mapfile

Any suggestion how get classes with no data?

Thanks Michal
