Do you mean classes with no representation in some map draw? There's no easy 
way. You'd
either 1) have to hack the source and extend the classObj to track 
precence/absence or
2) do your drawing at the shape level and assign (and presumably track) class 
membership
in MapScript.

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

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
