Batch File: String manipulation

Hi there,

I want to remove the following caracters from a variable \ : | < > & ^ " ! /.

Thanks for fixing my script,
Rene



@ECHO OFF

SETLOCAL enabledelayedexpansion

SET Title=T\h:i|s< >i&s ^a t"e!s/t:
SET Var=\,:,|,<,>,&,^,",!,/

FOR %%A IN (%Var%) DO SET Title=!Title:%%A=!

ECHO %Title%
PAUSE
EXIT

A lot of those characters are very special and are messing everything up.
First, in order to even get the special characters in Title to test you need to use ^ to escape them and get them in. Then you need to handle the ! first since it will kill parts of the string. At the same time, add quotes around the string so nothing else messes it up and remove them last.

Like this:
@ECHO OFF

SETLOCAL enabledelayedexpansion

SET Title=T\h:i^|s^< ^>i^&s ^^a t"e^!\s/t:
Set Title="%Title:!=%"
Set Title=%Title:|=%
Set Title=%Title:>=%
Set Title=%Title:<=%
Set Title=%Title:&=%
Set Title=%Title:"=%
echo %Title%
SET Var=\,:,/


FOR %%A IN (%Var%) DO SET Title=!Title:%%A=!

ECHO %Title%
PAUSE
EXIT

Oops. Line 12 is not needed and is a stray debugging line.

FWIW, this will also work:

SET Title=T\h:i^|s^< ^>i^&s ^^a t"e^!\s/t:
Set "Title=%Title:!=%"
Set "Title=%Title:|=%"
Set "Title=%Title:>=%"
Set "Title=%Title:<=%"
Set "Title=%Title:&=%"
Set "Title=%Title:\=%"
Set "Title=%Title::=%"
Set "Title=%Title:/=%"
Set "Title=%Title:"=%"
ECHO %Title%

Of course.
The idea of using the FOR loop was that it was easier to add more characters later. The only problem was that the FOR loop cannot be used on some of the special characters.

A slightly improved solution would have been:

@echo off

set title="T\h:i|s< >i&s ^a t"e!s/t:"
echo %title%

set title="%title:"=%"
set title=%title:>=%
set title=%title:<=%
set title=%title:|=%
set title=%title:^=%
set title=%title:&=%
set title=%title:\=%
set title=%title::=%
set title=%title:!=%
set title=%title:/=%
set title=%title:"=%
echo %title%

Open in new window


But I forgot to post this comment yesterday!

As you can see, there is no need to delay expansion of variables, no need to a FOR-loop and no need to precede 'special' characters with a ceret (^) - all that is merely required is to wrap your whole character string in double-quotes.

The only other thing to note is the order in which to substitute out characters - especially the first few.
