好吧，这是一个简单的脚本:

Well, here's a straightforward script:

@echo off
setlocal enabledelayedexpansion
set "INPUT_FILE=input.txt"
set "OUTPUT_FILE=output.txt"
set prev=
for /f "tokens=*" %%f in (%INPUT_FILE%) do (
    for /f "tokens=1,2 delims==" %%g in ("%%f") do (
        if "!prev!" neq "" (
            echo !prev! %%f >>%OUTPUT_FILE%
            set prev=
        ) else (
            if "%%g" equ "name" (
                set prev=%%f
            ) else (
                echo %%f >>%OUTPUT_FILE%
                set prev=
            )
