Thanks Daniel (and the others who replied). I've tried both ORO and Regexp, and gone with Regexp for the moment because it has the simplest API. FYI, the java.util.regex package describes its patterns as being "in a syntax similiar to that used by Perl". However I only use very limited regex functionality, Performance is not an issue for me; regex evaluation are not the bottleneck in this system.
