（已解决）批处理能处理文本中的段落，比如整个段落截取，或删除呢？

批处理能处理文本中的某个段落，比如整个段落截取，或删除呢？
比如还是这个文本，其中如下小节：

[AddReg]
HKLM,"SYSTEM\CurrentControlSet\Control\FileSystem","Ntfs",0x00010003,0x00000001
HKLM,"SYSTEM\CurrentControlSet\Control\FontAssoc","ANSI(00)",0x00000002,"YES"
HKLM,"SYSTEM\CurrentControlSet\Control\FontAssoc","SYMBOL(02)",0x00000002,"NO"
HKLM,"SYSTEM\CurrentControlSet\Control\FontAssoc","OEM(FF)",0x00000002,"YES"
...

[DelReg]
HKLM,"SYSTEM\CurrentControlSet\Services\fsvga"
HKLM,"SYSTEM\CurrentControlSet\Control\Nls\Locale","0402"
HKLM,"SYSTEM\CurrentControlSet\Control\Nls\Locale","0403"
HKLM,"SYSTEM\CurrentControlSet\Control\Nls\Locale","0404"
HKLM,"SYSTEM\CurrentControlSet\Control\Nls\Locale","0405"
HKLM,"SYSTEM\CurrentControlSet\Control\Nls\Locale","0406"
HKLM,"SYSTEM\CurrentControlSet\Control\Nls\Locale","0407"
HKLM,"SYSTEM\CurrentControlSet\Control\Nls\Locale","0408"
HKLM,"SYSTEM\CurrentControlSet\Control\Nls\Locale","0409"
...

我想将节“[AddReg]” 其下的所有内容全部截取到一个新文本中，或者删除节“[DelReg]” 及其所有内容，
该如何处理呢？

截取：

1. @set @n=0;/* & echo off
   
2. set "file=HIVESY.INF"
   
3. cscript -nologo -e:jscript "%~0"<"%file%">"New_%file%"
   
4. pause & exit/b & rem */
   
5. 
   
6. txt = WScript.StdIn.ReadAll();
   
7. re = /^\[AddReg][\s\S]+?(?=^\[)/img;
   
8. while ((ar = re.exec(txt)) != null) { WScript.Echo(ar) }

复制代码

删除：

1. @set @n=0;/* & echo off
   
2. set "file=HIVESY.INF"
   
3. cscript -nologo -e:jscript "%~0"<"%file%">"New_%file%"
   
4. pause & exit/b & rem */
   
5. 
   
6. txt = WScript.StdIn.ReadAll();
   
7. txt = txt.replace(/^\[Addreg][\s\S]+?(?=^\[)/img, "")
   
8. WScript.Echo(txt)

复制代码

如果[AddReg]节名连续出现，截取或删除[AddReg]节会出现遗漏
可能性虽然不大，还是改一下。

    截取：

1. @echo off & setlocal enabledelayedexpansion
   
2. set "file=HIVESY.INF"
   
3. set "key=[AddReg]"
   
4. (for /f "delims=" %%a in ('findstr /n .* "%file%"') do (
   
5.     set "str=%%a"
   
6.     set "str=!str:*:=!"
   
7.     if "!str:%key%=!" == "" (
   
8.         set flag=1
   
9.     ) else if "!str:~,1!" == "[" set "flag="
   
10.     if defined flag echo,!str!
    
11. ))>"New_%file%"
    
12. pause

复制代码

删除：
第10行改成：

1.     if not defined flag echo,!str!
