[文本处理] 如何实现从一个文本读取内容并替换掉另一个文本的指定字符串？

@echo off
(set /p 1-=&set /p -1=)<2号.txt
(set /p 2-=&set /p -2=)<3号.txt
(for /l %%i in (1 1 7) do (
	set/p %%i=
	setlocal enabledelayedexpansion
	for /l %%i in (1 1 50) do (set #= !#!)
	if %%i equ 3 (
		echo !#!^<Matrix tx="!1-!" ty="!-1!"/^>
	) else (
		if %%i equ 7 (
			echo !#!^<Matrix tx="!2-!" ty="!-2!"/^>
		) else (
			echo;!%%i!
		)
	)
	endlocal
))<1号.txt>$
move $ 1号.txt
