如何使用啟用的擴展擴展進行轉義

Question

寫一個簡單的腳本來查找和替換批處理中的字符。我的腳本包含“我想用諸如“。之類的文本替換它的字符。請讓我哪個轉義字符會有所幫助。嘗試過”“和^”腳本不起作用：`

    @echo off &setlocal 
    set search2="""
    set "replace2=""
    set "textfile=D:\Users\manajosh\Desktop\try-Copy.xml"
    set "newfile=D:\Users\manajosh\Desktop\Output.txt"
    (for /f "delims=" %%i in (%textfile%) do (
        set "line=%%i"
        setlocal enabledelayedexpansion
            set "line=!line:%search2%=%replace2%!"
            echo(!line!
        endlocal
    ))>"%newfile%"

pause 6

`

Answer 1

嘗試以下技術：

@echo off
set "search2=""
rem  set search2="""
set "replace2=""
set "line="quoted""
setlocal enableDelayedExpansion
 for /f "usebackq tokens=1,2 delims=§" %%a in ('"!search2!"§"!replace2!"') do echo "!line:%%~a=%%~b!"
endlocal

事情是您需要延遲擴展行以及search2和replace2-這可以通過包裝for循環來實現。
