如何通过bat批处理实现这样的文本样式转换？
一个文本文件内容包括很多段落。想通过bat批处理在这个文本文件每段的第一行前面加上“A：”，其他行前面加上“B：”。具体样式如下：
文本文件原样式是：
able
[having the power to do something]

about
[(1) almost; (2) of or having a relation to]
He completed about half of his work. (1)
We talk about the weather. (2)
above
[at a higher place]
His head was above the water.
…………
转换后的文本文件样式是：
A:able
B:[having the power to do something]
B:Are you able to speak English?
A:about
B:[(1) almost; (2) of or having a relation to]
B:He completed about half of his work. (1)

Can't understand why not use VBS, it will be much easier! Well, it's interesting to do this using CMD. The following is a possible solution.
REM --------START--------
@ECHO OFF
IF "%~1"=="" GOTO :EOF
ECHO 请稍后. . .
CD /D "%~dp1"
ECHO.>YOU_YOU
TYPE "%~1">>YOU_YOU
SET newName="%~n1_yy%~x1"
FINDSTR /N /V /R /C:"^[ ]*$" YOU_YOU>%newName%
SET /A n=1
SETLOCAL EnableDelayedExpansion
(FOR /F "usebackq delims=: tokens=1*" %%I IN (%newName%) DO (
IF %%I==!n! (ECHO B:%%J) ELSE (
SET /A d=%%I-n
FOR /L %%K IN (1,1,!d!) DO ECHO.
ECHO A:%%J)
SET /A n=%%I+1))>YOU_YOU
MORE +1 %newName%
DEL /Q YOU_YOU
START "" %newName%
REM --------END--------
Save above codes in a batch file, for example, "section.bat". You can put this file anywhere. If you wanna change some text file, DRAG it onto the icon of "section.bat", then everything will be done. Please Hi me if any problem!
