How to append the string from a specified line to a file - China DOS Union Forum

I have a bunch of data text files stored somewhat like this,

Identifier a: 1111 units
There may be N identifiers in between
Identifier b: 222 units
Separator
Identifier c: 333 units
Identifier c: 4444 units
Identifier d: 55 units

Characteristics of the text: identifiers may repeat, the length of each piece of data is not fixed, and the units for each kind may not necessarily be the same.
I want to find the data on the line below Separator in this kind of data text and append it to a file.

My idea is to first determine the line number X of Separator, read line X+1, and extract the needed data. Since I'm a newbie, after reading those posts in the sticky index I'm still kind of confused. The batch file I wrote below is also pretty clumsy, and it still has some problems: for example, if the data length changes, there's no way to record it accurately!

@echo off
setlocal
for /f "tokens=1,* delims=:" %%a in ('findstr /n /c:"分隔符" test.txt') do (
        set line=%%a
        )
set num=0
setlocal enabledelayedexpansion
for /f "skip=%line% delims=" %%i in (test.txt) do (
    set /a num+=1
    set var=%%i
    if !num! equ 1 echo !var:~7,3!>>num.txt
)
endlocal

I don't know which expert could help point me in the right direction and optimize this a bit.

Based on the additional requirements and goal the OP mentioned, I wrote this batch file. OP, give it a try; if it doesn't work, then reply and we can discuss it further. @Echo off&SetLocal EnableDelayedExpansion for /f "delims=" %%a in ('findstr ">.*<" ko_.html') do ( set "string=%%a" set "string=!string:>=＼!"&set "string=!string:<=＼!" if defined lxmxn (set "lxmxn="&&call :printf "!string!") else (echo !string!\|find "总帖数" >nul 2>nul&&set lxmxn=cn-dos) ) :end pause&exit/b :printf set hello=%~1 for /f "tokens=2 delims=＼" %%i in ("%hello%") do echo %%i exit/b

Tested it, works very well. If processing a lot of files, I guess it will take a long wait =.=
