Question

Is there any function/procedure as ReplaceString but for whole words on Delphi? I just need to replace substring to the new one when it\'s a whole word. For example

Answer 1

You can use the built-in regex library to do this. For example:

{$APPTYPE CONSOLE}

uses
  System.RegularExpressions;

const
  InputString = 'a Substring, substring123, some more text';

begin
  Writeln(TRegEx.Replace(InputString, '\bsubstring\b', 'newstring', [roIgnoreCase]));
end.
