我想提取像：

这样的句子

当她爬上车时，
当她爬回车里时，他们跑得很晚，
推着他的推车
'我们被卡住了，
和看到弗雷德和乔治的嫉妒面孔的前景
到达了系绳的末端。
今晚我会写信给你们的家人。
'你能相信我们的运气吗？'
'略过讲座'，
人们会谈论那个多年！'
'我知道我不应该喜欢这个或任何东西，但是 - '

我试图在regex101网站上这样做，但实际上每次都匹配所有。

任何人都可以帮助我吗？

Answer 1

试试这个：

^\|[^\w\|]*(\w+\s+(?=\w+)[^\|]*)

Explanation

^\|匹配
[^\w\|]*抓住任何不在a-z0-9和|
\w+\s+确保后跟一个单词和一个或多个单词白色空间
(?=\w+)然后检查是否有更多要关注的字词
[^\|]*如果找到先前的条件，那么抓住任何东西直到下一个管道|

Answer 2

你可以提出：

^\|                     # start of line, followed by |
(                       # capture the "words"
    (?:[‘\w]+           # a non-capturing group and at least one of \w or ‘
        (?:[^|\w\n\r]+  # followed by NOT one of these
        |               # or
        (?=\|)          # make sure, there's a | straight ahead
    )
){2,})                  # repeat the construct at least 2 times
\|

请参阅a demo on regex101.com（并注意修饰符！）这将至少捕获两个连续的字，如果您需要更多，请在{}括号中添加另一个数字。
