Replace 记事本++；双括号中的子表达式的regexp ID

我试图在记事本++中找到如下字符串：

'<a href="/mp3files/cards/Sentence With any Number of Words.mp3"></a>',

或另一种方法：

(cards/)([^\s]{1,50})([\s\.\?\!\-\,]{0,})([^\s]{1,50})

这两个都可以搜索，但我找不到替代品。 问题是一个句子中的字数可能不同。 我无法得到双括号中的子表达式的ID

以下替换格式：

\1\2\3…

不起作用，因为我无法获得双括号中子表达式的正确ID。

我试图用谷歌搜索这个主题，但什么也找不到。非常感谢任何建议、链接或最好的完整替换表达式。

这将用连字符和小写文件名替换

/cards/

之后的所有空格

• Ctrl+H
• 查找内容：

  （？：href=“/mp3files/cards/|\G）\K（？）.mp3）（\S+（:\h+）（\.mp3））

• 替换为：

  \L$1（？2$2:-）

• 检查环绕
• 检查正则表达式
• 全部替换

说明：

(?:                     # non capture group
    href="/mp3files/cards/  # literally
  |                       # OR
    \G                      # restart fro last match position
)                       # end group
(?!\.mp3)               # negative lookahead, make sure we haven't ".mp3" after this position
\K                      # forget all we have seen until this position
(\S+)                   # group 1, 1 or more non spaces
(?:                     # non capture group
    \h+                     # 1 or more horizontal spaces
  |                       # OR
    (\.mp3)                 # group 2, literally ".mp3"
)                       # end group

\L$1            # lowercase content of group 1
(?2             # if group 2 exists (the extension .mp3)
    $2              # use it
  :               # else
    -               # put a hyphen
)               # endif

更换：

(?:                     # non capture group
    href="/mp3files/cards/  # literally
  |                       # OR
    \G                      # restart fro last match position
)                       # end group
(?!\.mp3)               # negative lookahead, make sure we haven't ".mp3" after this position
\K                      # forget all we have seen until this position
(\S+)                   # group 1, 1 or more non spaces
(?:                     # non capture group
    \h+                     # 1 or more horizontal spaces
  |                       # OR
    (\.mp3)                 # group 2, literally ".mp3"
)                       # end group

\L$1            # lowercase content of group 1
(?2             # if group 2 exists (the extension .mp3)
    $2              # use it
  :               # else
    -               # put a hyphen
)               # endif

哇，太简单了，非常感谢！再次感谢，托托（投票表决）。您能在替换中添加小写字母的更改吗？@Ken：有点复杂，请看我的编辑。托托，非常感谢。这对我来说真的很有帮助，也很有教育意义。
