正则表达式：连接/连接 html 标签中用空格分隔的单词中的字母

Question

我有这个 HTML 标签：

<title>c o n n e c t s t h e l e t t e r s i n w o r d s</title>

必须成为：

<title>connects the letters in words</title>

我尝试了这个，但是没有用：

寻找：(<title>)(.+?\s+.+?)(</title>)

替换为：\1\2\3

Answer 1

• Ctrl+H
• 找什么：(?:<title>|\G)\S*\K(?:\h+(\h)|\h+)(?=.*</title>)
• 用。。。来代替：$1
• 查看 环绕
• 查看 正则表达式
• Replace all

解释：

(?:         # non capture group
    <title>     # literally, open tag
  |           # OR 
    \G          # restart from last match position
)           # end group
\S*         # 0 or more non space
\K          # forget all we have seen until this position
(?:         # non capture group
    \h+         # 1 or more horizontal space
    (\h)        # group 1, 1 horizontal space
  |           # OR
    \h+         # 1 or more horizontal space
)           # end group
(?=         # positive lookahead, make sure we have, after:
    .*          # 0 or more any character
    </title>    # literally, close tag
)           # end lookahead
