test.bat is as below

 

@echo off
setlocal enabledelayedexpansion
：：变量延迟开启，for语句
REM devcon.exe status * >devinfo.txt
for /f "delims=: tokens=1,*" %%i in ('findstr /n /c:"Device has a problem" devinfo.txt') do (
　　 rem  　343:    Device has a problem: 28. this is separated by ":", %%i is 343, %%j is Device has a problem: 28.　
     echo %%j>>result.txt
    set  flag=1
    set  line=%%i
    call :twoline 
)
goto :eof

:twoline 
    REM  Two lines need to be searched, like ''ACPI\NXP5442\1
    REM                                                            Device has a problem: 28
    set /a line=line-1
    for /f "tokens=1,* delims=:" %%i in ('findstr /n .* devinfo.txt') do (
    rem  search from full log, also delimited by ":"
    if  %line% equ %%i  (

        set flag=0
        goto :twoline
        )   else (goto :eof)

 output with being:
