Solve : extract string from a environment variable?

Answer»

I have many environment variables with value like testfilename.txtsomethingelse. The length of somethingelse is not
constant and neither the part before .txt for each of those variables.

I want to remove the string before .txt or the string after .txt of all those variables.

Is there a way to use wildcard to extract the string after .txt?

Can I do somthing like SET a=%b:*.txt=%

I know this is not correct, would any experts give some ideas ?
Provided the .txt stays constant, this should work:

Code: [SELECT]@echo off
for /f "tokens=1-2 delims=." %%a in ("testfilename.txtsomethingelse") do (
set var2=%%a
set var=%%b
)
set var=%var:~3%
echo %var2% %var%

For a more robust solution, TRY Windows Script

Hope this helps. 8-)

Note: you can replace testfilename.txtsomethingelse with any environment variable (SURROUNDED by %); keep the quotes.You are really cool 8-)

THANKS very much!
