DIPcre is a powerful regular expression engine for Boland Delphi 4/5/6/7 that includes two regular expression controls (TDIPcreEdit and TDIPc) and is compatible with Perl 5.

But that's not all. DIPcre also comes with two regular expression edits: TDIPcreEdit and TDIPcreComboBox. These are similar to Delphi's TMaskEdit, but more powerful as they validate user entry against a regular expression pattern.
One of the biggest advantages of DIPcre is that it utilizes *.obj files compiled from the PCRE C-library, which compiles straight into your executable file. In fact, Borland chose PCRE to ship with its C++ Builder, making DIPcre the most powerful regular expression library for Delphi, whether you're looking for freeware or commercial options.
