我真的想知道为什么我的字符串替换过程在解析包含任何特殊字符(包括感叹号)的文本文件时有效.我预计延迟变量扩展会关闭&符号,百分号等的特殊含义,但会因感叹号而失败...

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
