Batch Processing for reading rows with sensitive characters

CopyCode The Code is as follows: @ echo off
: Normal for + findstr statements ignore rows starting with a semicolon
: Findstr/n. * after delims =: is used, all colons at the beginning of the line are ignored.
: Yes! , &,. And other special symbols need to be processed
: The following code accurately extracts these sensitive characters:
: Solved the problem of setlocal maximum recursion layer (this problem occurs when setlocal nesting processes more than 15 rows of content)
: Empty rows can be calculated.

Goto: EOF
@ Echo off
: When there are more than 15 lines of content, it will bring about the setlocal maximum recursion layer problem.
