[文本处理] 替换文本内容的批处理为什么有几行字不会打印出来？

这里是原始文本的其中一段

想用这个代码来替换文本里面的内容，其他内容都没问题，就上面那一段会莫名其妙的都消失了

for /f "delims=" %%i in (3.ass) do (
    set n=%%i
    call set n=%%n:xxxxxxxx=yyyyyyyyyy%%
    call echo %%n%%>>4.ass
)
复制代码

用type来查看文本，貌似windows也能正确读取文本，不懂为什么会这样

那是因为这些行列中有特殊字符&，要处理它就要开启变量延迟：

@echo off&setlocal enabledelayedexpansion
(for /f "delims=" %%a in (3.asss) do (
  set "str=%%i"
  echo !str:xxxxxxxx=yyyyyyyyyy!
))>4.asss

俺学艺不太行啊，再来求教

按版主那样改之后 只能输入一条 替换命令，输入第二条之后就无效了，为什么
echo !str:xxxxxxxx=yyyyyyyyyy!
echo !str:xxxxxxxx=yyyyyyyyyy!(失效)
echo !str:xxxxxxxx=yyyyyyyyyy!(失效)

好像不能多输入几条，原来我那个代码是可以
call set n=%%n:xxxxxxxx=yyyyyyyyyy%%
call set n=%%n:xxxxxxxx=yyyyyyyyyy%%
call set n=%%n:xxxxxxxx=yyyyyyyyyy%%
这样多几条的
