我真的不知道为什么解析包含任何特殊字符包括感叹号文本文件时,我的字符串替换程序的工作原理。 我预计延迟变量扩展将关闭符号,百分号等特殊的含义,但反而会失败感叹号...
码:
@echo on & setlocal ENABLEEXTENSIONS
set "InFile=%~1"
set "OutFile=%~2"
set "Replace=%~3"
CALL :ParseCue "%%InFile%%" "%%OutFile%%" "%%Replace%%"
endlocal &GOTO:EOF
:ParseCue
@echo on & setlocal ENABLEEXTENSIONS DISABLEDELAYEDEXPANSION
set "FileToParse=%~1"
set "OutputFile=%~2"
set "NewExtension=%~3"
for /F "usebackq tokens=* delims=" %%a in ("%FileToParse%") DO (
set "line=%%a"
@echo on & setlocal ENABLEEXTENSIONS ENABLEDELAYEDEXPANSION
set "line=!line:.wav=%NewExtension%!"
echo(!line!>>"%OutputFile%"
endlocal
)
endlocal &GOTO:EOF
InputFile.txt:
This a test for parsing lines with special characters
Rock & Roll.wav
Rock & Roll!.wav
Special | < > ~ \ ²³ { [ ] } ! " ´ ' ` üäö @ ; : € $ % & / ( ) = ? chars.wav
命令行语法:
D:\Users\Public\Batch\YAET>parse.bat "InputFile.txt" "OutputFile.txt" ".flac"
OutputFile.txt:
This a test for parsing lines with special characters
Rock & Roll.flac
Rock & Roll!.flac
Special | < > ~ \ ²³ { [ ] } ! " ´ ' ` üäö @ ; : € $ % & / ( ) = ? chars.flac
编辑/补充:
经过1年半我不得不再次使用该代码段。 看到两个额外的例子处理毒字符。 首先一个临时启用再次推迟扩大(见Ansgars答案),使用第二个CALL
。 双方将解析的非空的文件路径和名称,并在当前目录下,但没有尾随驱动器号和路径到当前目录下。
示例#1(括在双引号set "File=!File..."
和echo "!FILE!">>...
不要求):
@echo off & setlocal ENABLEEXTENSIONS DISABLEDELAYEDEXPANSION
del NonEmptyFiles.txt >NUL 2>&1
echo Searching non-empty files in and below current directory ...
for /f "tokens=*" %%I in ('dir /s /b /a:-D') do (
if not %%~zI==0 (
set "File=%%I"
setlocal ENABLEDELAYEDEXPANSION
set "File=!File:%cd%\=!"
echo "!File!">> NonEmptyFiles.txt
endlocal
)
)
echo Done. See NonEmptyFiles.txt.
endlocal &goto:EOF
实施例#2(慢,包封双引号需要):
@echo off & setlocal ENABLEEXTENSIONS DISABLEDELAYEDEXPANSION
del NonEmptyFiles.txt >NUL 2>&1
echo Searching non-empty files in and below current directory ...
for /f "tokens=*" %%i in ('dir /s /b /a:-D') do (
if not %%~zi==0 (
set "File=%%i"
call set "File=%%File:%cd%\=%%"
call echo "%%File%%">> NonEmptyFiles.txt
)
)
echo Done. See NonEmptyFiles.txt.
endlocal &goto:EOF
文件和文件夹进行测试:
D:\Martin\Any & Path>dir /s /b /a:-D
D:\Martin\Any & Path\Hello! World!.txt
D:\Martin\Any & Path\Rock & Roll\!File! !!File!!.txt
D:\Martin\Any & Path\Rock & Roll\%File% %%File%% %%I.txt
D:\Martin\Any & Path\Rock & Roll\Poison! !§$%&()=`´'_;,.-#+´^ßöäüÖÄÜ°^^#.txt
D:\Martin\Any & Path\Rock & Roll\SizeZero.txt
输出:
D:\Martin\Any & Path>stringinforloop.bat
Searching non-empty files in and below current directory ...
See NonEmptyFiles.txt. Done.
D:\Martin\Any & Path>type NonEmptyFiles.txt
"Hello! World!.txt"
"Rock & Roll\!File! !!File!!.txt"
"Rock & Roll\%File% %%File%% %%I.txt"
"Rock & Roll\Poison! !§$%&()=`´'_;,.-#+´^ßöäüÖÄÜ°^^#.txt"
