删除批处理（.bat）文件中的部分字符串

Question

我需要删除部分字符串，以便我可以使用该消息。尝试了许多不同的方法失败了。提前致谢

想象我有这样一条消息：

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

我需要删除它：

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

得到这样的东西：

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

请注意＆＃34; in＆＃34;之间的文字。和＆＃34; Keyref＆＃34;是变量，这意味着我必须找到一种方法来删除这两个字符串之间的文本（包括）。

Answer 1

试试这个：

@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%

Answer 2

假设in和Keyref只出现一次，|永不出现，那么：

@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
