I used contains because filter could have the value

didn't work.

No, you're right, = won't work for this, in XSLT 1.0.

Yet another reason among many to prefer XSLT 2.0 for this kind of thing is that it makes this sort of problem considerably more tractable:
"tokenize(@filter,',\s*') = ('filter1','filter10')".

It's much harder to deal with in unextended XSLT 1.0: you either have to work with very carefully constrained values, or get into recursive templates to handle the strings. Or both. Or model the information in a way more amenable to XSLT 1.0.
