Can batch processing achieve this?

Can someone help? Thank you very much

Using batch processing is terrible and difficult because of special characters

@echo off
for /f "tokens=* delims=:" %%a in ('findstr /n "\.asp" a.txt') do (
set var=%%a
setlocal enabledelayedexpansion
set var=!var:*:=!
set var=!var:*"=!
set var=!var:"= !
if not "!var!"=="" for /f "delims= " %%i in ("!var!") do if "%%~xi"==".asp" (>>bak.txt echo %%i)
endlocal
)
pause

I spent about an hour, and I can only say it's too difficult. Many things can't be extracted. The main thing is the situation is too complicated.

Thank you very much. Can you help me write the comments for the just batch processing? It's better to be detailed. Thanks

No good way, the file name cannot contain the # sign.
:

@echo off

for /f "delims=" %%i in ('findstr /i "\.asp" a.txt') do (

  set "var=%%i"

  setlocal enabledelayedexpansion

  set var=!var:"=!

  set var=!var:#=!

  set var=!var:"=!

  set var=!var:^>=!

  set var=!var:^<=!

  set var=!var:/==!

  set var=!var:.asp=#!

  call :loop

  endlocal

)

start b.txt

exit

:loop

for /f "delims=#" %%a in ("!var!") do call :lis "%%a"

goto :eof

:lis

for /f "tokens=1* delims==" %%a in ("%~1") do (

  if not "%%b"=="" (call :lis "%%b") else >>b.txt echo %%a.asp

)

goto :eof

@echo off
for /f "tokens=* delims=:" %%a in ('findstr /n "\.asp" a.txt') do (
set var=%%a
setlocal enabledelayedexpansion
set var=!var:*:=!
set var=!var:*"=!
set var=!var:"= !
set var=!var:?= !
set var=!var:^>= !
set var=!var:^<= !
if not "!var!"=="" for /f "tokens=1* delims= " %%i in ("!var!") do if "%%~xi"==".asp" (>>bak.txt echo %%i) else call :lp "%%j"
endlocal
)
pause
goto :eof
:lp
for /f "tokens=1* delims= " %%i in ("%~1") do if "%%~xi"==".asp" (>>bak.txt echo %%i&goto :eof) else call :lp "%%j"

Just sent it and then realized it was already there

Why not directly:

grep -oE "\w+\.asp" urfile.html

　At the request of the poster and to the best of my ability, the following is the explanation for TERSE's wonderful code (please forgive and give advice if there are errors and deficiencies):
　The batch processing first uses the first for loop to enable variable delay, uses ":" as the delimiter to replace special characters (:"") in each segment of the string in a.txt with nothing, and replaces special characters (?><) with space " " (this is to prepare for the delims= in the subsequent for loop);
　Then, it performs an if judgment on the replaced string to see if it is empty. If it is not empty, it enters the second for loop, and again uses if to judge the first string %%i with " " as the delimiter to see if there is a file name with.asp as the suffix name (here, variable expansion %%~xi is used to expand variable %%i to the file extension). If there is, it adds this string (%%i) to the input back.txt. If not (else), it jumps to the next for loop with the label lp, and passes the substring "%%j variable" after %%i to the next for loop (note that enclosing %%j in double quotes here is to enable the next for loop to correctly identify the variable %%j with spaces);
　In the last for loop, it is actually constantly repeating the work of the previous for loop until the last string with.asp as the suffix is taken out and added to back.txt. It's just that here, %%~1 is used to remove the double quotes of the variable and expand the variable %%~1 (the variable "%%j" with double quotes passed from the previous for loop).
　Another very difficult process to explain, sweat......

If it were me, I would use Python to parse it. It's still quite simple, and of course, the efficiency is higher than batch processing...

For handling this problem, VBS is simpler and more efficient. Why stick to one option only?

I disagree with the opinions of abcd. We are dealing with this problem to achieve improvement, and for no other reason.
