This regexp library can only (under xBase++) return boolean values (TRUE or FALSE) dependant upon the success of the search.

It consists of an Xbase++ class which wraps a C++ DLL based on Henry Spencer.
If you need to find the location of data using regular expressions, then you must use XbPCRE. If however, you only need to know whether the token exists, then this library may prove faster and simpler to use.
