如何通过搜索＆＃39; =＆＃39;来替换文本行使用.bat脚本在文件中的符号？

Question

如何使用＆＃39; =＆＃39;进行搜索来替换文本行使用.bat脚本的文件中的符号？

我有一个文本文件test.txt，文字为

=============================================== ==

PATH=C:\ProgramFiles\Think\Digit\Trunk.exe 

WORD=C:\ProgramFiles\Microsoft\Word12\Word.exe

=============================================== ==

我可以替换文本＆＃34; C：\ ProgramFiles \ Think \ Digit \ Trunk.exe＆＃34;用这个词，＆＃34;删除＆＃34; ..........

但是，我想通过搜索来替换整行............ PATH = C：\ ProgramFiles \ Think \ Digit \ Trunk.exe .......使用变量SEARCHTEXT。但是，我无法使用＆＃39; =＆＃39;操作

我的批处理文件包含以下代码： -

=============================================== ===================================

@echo off

setlocal enabledelayedexpansion

set INTEXTFILE=C:\Users\PrasanthReddy\Desktop\test.txt

set OUTTEXTFILE=C:\Users\PrasanthReddy\Desktop\testsimple.txt

set SEARCHTEXT=C:\ProgramFiles\Think\Digit\Trunk.exe

set REPLACETEXT=Deleted

set OUTPUTLINE=


for /f "tokens=1,* delims=¶" %%A in ( '"findstr /n ^^ %INTEXTFILE%"') do (

   SET string=%%A

   for /f "delims=: tokens=1,*" %%a in ("!string!") do set "string=%%b"

   if  "!string!" == "" (

       echo.>>%OUTTEXTFILE%

   ) else (

      SET modified=!string:%SEARCHTEXT%=%REPLACETEXT%!

      echo !modified! >> %OUTTEXTFILE%

  )

)

del %INTEXTFILE%
rename %OUTTEXTFILE% %INTEXTFILE%

=============================================== ============================

任何人都可以帮我改变它......我怎么能这样做....

不是输出具有替换值的字符串，而是确定替换是否已完成，并根据结果回显已确定的值

@echo off
    setlocal enableextensions disabledelayedexpansion

    set "INTEXTFILE=C:\Users\PrasanthReddy\Desktop\test.txt"
    set "OUTTEXTFILE=C:\Users\PrasanthReddy\Desktop\testsimple.txt"

    set "SEARCHTEXT=C:\ProgramFiles\Think\Digit\Trunk.exe"
    set "REPLACETEXT=Deleted"

    (   for /f "tokens=1,* delims=:" %%a in ('findstr /n "^" "%INTEXTFILE%"'
        ) do if "%%b"=="" (
            echo(
        ) else (
            set "string=%%b"
            setlocal enabledelayedexpansion
            if "!string:%SEARCHTEXT%=!"=="!string!" (
                endlocal
                echo(%%b
            ) else (
                endlocal
                echo(%REPLACETEXT%
            )
        )
    ) > "%OUTTEXTFILE%"

    move /y "%OUTTEXTFILE%" "%INTEXTFILE%"
