Here is a pretty simple way of handling it
unit Unit1;
interface
uses
Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
Dialogs, StdCtrls;
type
TForm1 = class(TForm)
Memo1: TMemo;
Button1: TButton;
procedure Button1Click(Sender: TObject);
private
function removeCharacters( const pText: string;
const pCharacters: array of char): string;
public
{ Public declarations }
end;
var
Form1: TForm1;
implementation
{$R *.dfm}
function TForm1.removeCharacters( const pText: string;
const pCharacters: array of char): string;
var
i: integer;
begin
result := pText;
for i := 0 to high( pCharacters) do
result := stringReplace( result, pCharacters[ i], '', [ rfReplaceAll]);
end;
procedure TForm1.Button1Click(Sender
begin
memo1.text := removeCharacters( memo1.text, [ '[',']','(',')']);
end;
end.
Thanks for the accepted solution status even though my regexp I slapped together was not right. :( I would have replied sooner but was out. :) Glad you worked it out. the pearlregexp is something I consider the key part of most of my applications and cannot live without. :)
Another great thing is Regular Expression Buddy (just google it). Makes life so easy!

I use Regular Expressions in most of my Delphi programming. Too handy for search and replace to not.
My advice (and I am sure it is not the best way if you do not use it for more) is to get tPerlRegEx (t'is free at http://www.regular-express
Just match on '\[([^\]]*)]' and replace the result grouped result with an empty string. Then do it again with '\(([^\)]*))'
I am sure ppl out there can create a better regex search and I could combine the 2 searches into 1 by ORing what I am looking for and using a backreference, but I like to keep them all simple. ;)
