[文本处理] 批处理如何提取文本中双引号内的特定内容？

@echo off&setlocal enabledelayedexpansion
(for /F "delims=" %%a in (1.txt) do (
set "a=%%a"&set "a=!a:"=$!"
for /F "tokens=2 delims=$" %%b in ("!a!") do echo.%%b
))>2.txt
复制代码

@echo off
for /f "tokens=3 delims== " %%i in (a.txt) do echo %%~i
pause
复制代码

@echo off
for /f tokens^=2^ delims^=^" %%a in (a.txt) do echo %%a
pause>nul
复制代码

@echo off
(for /f tokens^=2^ delims^=^" %%i in (test.txt) do echo %%i )>2.txt
rem 复习一下用"作为分隔符，竟然忘记了对空格进行转义——学而时习之！
pause>nul
复制代码

powershell -c "gc '文本.txt'|%%{$_.split('\"')[1]}"
pause
复制代码

powershell -c "([regex]'(?<=<host name="")[^\"]+').Matches([IO.File]::ReadAllText('文本.txt', [Text.Encoding]::default))^|%%{$_.Value}"
pause
复制代码

powershell -c "[IO.File]::ReadAllText('文本.txt', [Text.Encoding]::default)|Select-String '(?<=<host name="")[^\"]+' -AllMatches^|%%{$_.matches^|%%{$_.Value}}"
pause
