I would like to interpolate a string like "$attribute == value" into an if statement, but actually more complex, using and, or and not operators. Is that possible in some simple way, or do I have to use perl-byacc for that (I don't have yacc knowledge, so that would be kinda complicated)?

Thanks, Lori

PS.: What I actually want to implement is the Perl equivalent of the ethereal-filter(4) mechanism.
