Remove part of a string in a Batch (.bat) file

Question

I need to remove part of a string so I can use the message. Tried many different ways unsuccessfully. Thanks in advance

Immagine that I have a message like this one:

SET MESSAGE="The key sequence '1' in 'http://www.myschema.com/dummy:dummy_PK' Keyref fails to refer to some key."

I need to remove this:

in 'http://www.myschema.com/dummy:dummy_PK' Keyref

And get something like this:

"The key sequence '1' fails to refer to some key."

Do note that the text between "in" and "Keyref" is variable, meaning I have to find a way to remove the text between these 2 strings (inclusively).

Answer 1

Assuming in and Keyref only appear once, and | never appears, then:

@echo off
setlocal enableDelayedExpansion
set message="The key sequence '1' in 'http://www.myschema.com/dummy:dummy_PK' Keyref fails to refer to some key."
set "message=!message: in =|!"
set "message=!message: Keyref =|!"
for /f "delims=| tokens=1,3" %%A in ("!message!") do set "message=%%A %%B"
set message

Answer 2

Try this:

@echo off
setlocal

SET "MESSAGE=The key sequence '1' in 'http://www.myschema.com/dummy:dummy_PK' Keyref fails to refer to some key."
SET "sFind=in 'http://www.myschema.com/dummy:dummy_PK' Keyref "
call set New=%%Message:%sFind%=%%
echo %New%
