TRegExpr v.0.952 - Delphi Regular Expressions
First of all I recommend You to read articles with usage illustrations.
Please, note that there are localized demos available (with comments in source code on national languages). This localized versions distributed in localized full TRegExpr packages, and in separate localized documentation packages (when You unpack this documentation package in TRegExpr directory the localized demos overwrite English ones).
very simple examples, see comments inside the unit
slightly more complex examples, see comments inside the unit
If You don't familiar with regular expression, please, take a look at the r.e.syntax topic.
TRegExpr interface described in TRegExpr interface.
Some of demo-projects use extended VCL properties which exists only in Delphi 4 or higher. While compiling in Delphi 3 or Delphi 2 you'll receive some error messages about unknown properties. You may ignore it - this properties is needed only for resizing and justification of components then form change it's size.
