如何替换/删除字幕（文本）文件中的特定行？

Question

到目前为止，我已经创建了一个批处理文件，该文件为文件添加后缀＆＃39;所选文件夹中的名称，类型为：

1. *。AVI
2. *。MKV
3. *。MP4
4. *。驴

现在，我想添加选项以通过*.srt / *.ass文件（字幕文件）搜索特定文本，并删除包含找到的文本的行（如果它存在的话）在文件中）。我还想选择用另一个替换找到的文本。

我希望我所要求的是可能的，并且非常感谢您提供的任何帮助。

到目前为止我的代码：

@if (@CodeSection == @Batch) @then


@echo off
setlocal EnableDelayedExpansion

rem Select the folder via WSH Shell.Application BrowseForFolder method
for /F "delims=" %%a in ('cscript //nologo //E:JScript "%~F0"') do set "folder=%%a"
if not defined folder goto :EOF
cd "%folder%"

for /F "delims=" %%a in ('dir /B /A-D *.avi *.mkv *.mp4 *.ass ^| findstr /I /V ".created_by_me"') do (
   set "fileName=%%a"

   rem Convert the file name to lowercase letters
   for %%a in (a b c d e f g h i j k l m n o p q r s t u v w x y z) do (
      set "fileName=!fileName:%%a=%%a!"
   )

   if "!fileName!" equ "%%a" (
      rem The original file name have all lowercase letters
      ren "%%a" "%%~Na.created_by_me%%~Xa"
   ) else (
      rem The original file name include at least one uppercase letter
      ren "%%a" "%%~Na.Created_By_Me%%~Xa"
   )

)
goto :EOF


@end


// JScript section

var shl = new ActiveXObject("Shell.Application");
var folder = shl.BrowseForFolder(0, "Please choose a folder.\nThis extension will add a \".HebSubs-Tvil.Me\" suffix to each file of the following types: *.ASS; *.AVI; *.MKV; *.MP4", 0, 0x00);
WSH.echo(folder ? folder.self.path : "");
