https://website23.com/anotherimage.png,Artis Name,Heavy Metal,www.website5/music/mymusicmetal.mp3

www.website63.com/singerimage.png,Artis Name,Jazz,https.website5/music/mymusicjazz

如何使用记事本++做到这一点？

Answer 1

您可以在Notepad ++上使用正则表达式，并使用反向引用

(([^\r\n]+))(\r\n)?(([^\r\n]+))(\r\n)?

更新：(([^\r\n]+))([\r\n])?(([^\r\n]+))([\r\n])? ..这会忽略换行符类型

\ 1-第一行网址

\ 4-第二行网址

\ 3-新行来自第3组

仅供参考：请勿多次运行（全部替换）。它将继续替换

Answer 2

这将合并由单个换行符分隔的行。

• Ctrl + H
• 查找内容：^.+\K\R(?!\R)
• 替换为：,
• 检查 环绕
• 检查 正则表达式
• 取消检查 . matches newline
• 全部替换

说明：

^                   # beginning of line
  .+                # 1 or more any character but newline
  \K                # forget all we have seen until this position
  \R                # any kind of linebreak (i.e. \r, \n, \r\n)
  (?!\R)            # negative lookahead, make sure we haven't a linebreak after
