TPerlRegExMatchedText (Delphi)

Description

This example uses the MatchedText property. This example assumes that you have placed a TLabel on a form, made a global TPerlRegEx variable and instantiated it in init code.

Code

procedure TForm1.Button1Click(Sender: TObject);
begin
  with PerlRegEx1 do begin
    RegEx := 'Windows|Linux';  // Matches 'Windows' or 'Linux', whichever comes first
    if Match then Label1.Caption := MatchedText + ' came first!';
  end;
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
  PerlRegEx1:= TPerlRegEx.Create;
  PerlRegEx1.Subject := 'This is a Linux or a Windows App.';
end;
