英文:
Regular expression. How to get strings from text?
问题
在第一种情况下，这些行位于
> "\n 和 \
在第二种情况下，这些行位于
> message\n 和 \
之间可以有任意数量的行。
如何通过单个查询选择/获取这些字符串？
我希望有人能够编写一个适当的正则表达式。
我可以使用以下正则表达式
("\n|message\n)+(.*\n.*\n)
我想要的文本位于第二组中，但仅限于两行。我不知道如何编写一个适用于任意行数的表达式，以及如何添加一个以
(\\n) 或 (^\\) 结束的条件。
英文:
There is a text:
"
Sample text 1!
,,Sample&.,? text 2?
\
-message
32 Another sample text 3
... sample text 4&
!Sample text 5%
\

In the first case, the lines are between
> "\n and \
In the second, the lines are between
> message\n and \
There can be any number of lines in between.
How can I select/get these strings in a single query?
I hope someone will write a proper regular expression.
I can do this
("\n|message\n)+(.*\n.*\n)
The text I want is in the second group but it's only for two lines. I don't know how to write a expression for any number of lines and how to add a condition that ends with
(\\n) or (^\\)

你正在寻找 _单行_ 模式，即 `s`。
在这种模式下，`.` 会匹配换行符。
这里的 `\s+?^` 用于跳过换行符，以便它们不在 _捕获组_ 内。
```none
/(?:-message|")\s+?^(.+?)\s+?^\\/gms

You are looking for single-line mode, s.
This is where a . will additionally match new-line delimiters.
The \s+?^ here is used to skip-over the new-line delimiters, so they are not within the capture group.
/(?:-message|")\s+?^(.+?)\s+?^\\/gms
