DIRegEx is a library of Delphi (Embarcadero / CodeGear / Borland) components and procedures that implement regular expression pattern matching using the same syntax and semantics as Perl 5.10, with just a few differences. This includes support for UTF-8 encoded strings and Unicode general category properties.
DIRegEx offers two regular expression algorithms with their corresponding wrapper classes for easy usage:
- TDIDfaRegEx implements the DFA matching algorithm. Considerer this as a special purpose algorithm. If finds all possible matches and in particular, it finds the longest. It never needs to backtrack and supports partial matching much better, even for very long subject strings in several pieces.
