/。如果没有换行符，*/效果很好。如果它必须匹配换行符，这里有一些解决方案:

我用这个:(.|\n)+对我来说就像一个魅力!

(.*?)匹配任何东西-我已经使用它很多年了。

Regex: /I bought.*sheep./ Matches - the whole string till the end of line I bought sheep. I bought a sheep. I bought five sheep. Regex: /I bought(.*)sheep./ Matches - the whole string and also capture the sub string within () for further use I bought sheep. I bought a sheep. I bought five sheep. I boughtsheep. I bought a sheep. I bought fivesheep. Example using Javascript/Regex 'I bought sheep. I bought a sheep. I bought five sheep.'.match(/I bought(.*)sheep./)[0]; Output: "I bought sheep. I bought a sheep. I bought five sheep." 'I bought sheep. I bought a sheep. I bought five sheep.'.match(/I bought(.*)sheep./)[1]; Output: " sheep. I bought a sheep. I bought five "

选择并记住以下1个!!：）

[\s\S]*
[\w\W]*
[\d\D]*

解释:

\s:没有空白

\w:字\w:不字

\d:数字\d:不是数字

(如果你想要1个或更多字符[而不是0个或更多]，可以将*替换为+)。

附加编辑:

如果你想匹配一行中的所有内容，你可以使用这个:

[^\n]+

解释:

^:不

\ n: linebreak

+:表示1个字符或更多

(.*?)不适合我。我试图匹配注释周围的/* */，其中可能包含多行。

试试这个:

([a]|[^a])

这个正则表达式匹配a或除a之外的任何东西，当然，它意味着匹配所有东西。

顺便说一句，在我的情况下，/\*([a]|[^a])*/匹配C风格的注释。

感谢@mpen提供了一个更简洁的方式。

[\s\S]
