ABSTRACT:
A mechanism is provided to facilitate complex textual pattern matching. Regular expressions are specified utilizing a set of rules of various simplicity/complexity. These rules are subsequently employed to generate a more complex regular expression described by the rules, which can be passed to a regular expression engine to identity textual patterns as a function thereof.
