Replace a substring with the contents of a variable

[cocoabsb]

Hi,

See the following piece of code:

set str=teh cat in teh hat
echo.%str%
set str=%str:teh=the%
echo.%str%

How can I use variables instead of teh and the in the line "set str=%str:teh=the%" ?

I have tried this:
set str=teh cat in teh hat
echo.%str%
var1=teh
var2=the
set str=%str:%var1%=%var2%%
echo.%str%

but it did not work.

How can this be done?

Thanks

This should work.

Code: Select all

set str=teh cat in teh hat
echo.%str%
var1=teh
var2=the
call set "str=%%str:%var1%=%var2%%%"
echo.%str%

Or this one...

Code: Select all

setlocal EnableDelayedExpansion
set str=teh cat in teh hat
echo.%str%
var1=teh
var2=the
set str=!str:%var1%=%var2%!
echo.%str%
