Perl 5.003 doesn't have zero-width lookbehind assertions, so neither does jakarta-oro at the moment, but it should definitely before the end of the year. Lookbehind assertions were introduced in Perl 5.005. However, what you are describing, (?!regexp), is a zero-width negative lookahead assertion. jakarta-oro implements both zero-width negative and positive lookahead assertions. daniel
