"aaa","ccc","",,,,"aaa","",,,,
替换成：
aaa|ccc|||||aaa|||||
如何用批处理来做啊？
版主曾给我写出：
@echo off & setlocal

for /f "delims==" %%i in (IND_INFO.txt) do (
for %%k in (%%i) do for %%c in (%%~k) do set/p a=%%c^|<nul
echo.
)>>aa.txt
这样的语句来做，但这句话把Ｎ个并排的逗号，都替换成１个| ....
请帮忙解决一下　，谢谢！

@echo off
set a="aaa","ccc","",,,,"aaa","",,,,
set a=%a:,=^|%
setlocal enabledelayedexpansion
echo !a:^"=!
endlocal
pause

这个表里面很多字段呢。而且替换出来一个新的文本。。。。

你这样写，我不知道怎么替换整个表啊。。。。。。。。。。

你这样说我不知道怎么写

哦。你是要这样？不过我保留了 "
@echo off & setlocal EnabledelayedExpansion

set a="a","b",,"cc",,,"ddd",,,,

for /l %%i in (0,1,1024) do (

set "c=!a:~%%i,1!"
if "!c!"=="" goto :output
echo !c!
if "!c!"=="," (
set b=!b!^|
) else (
set "b=!b!!c!"
)
)
:output
echo !b!

pause
