我用这个:(.|\n)+对我来说就像一个魅力!

我用这个:(.|\n)+对我来说就像一个魅力!

(.*?)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]

因为。查找单个字符，换行符或行结束符除外。

所以，要匹配任何东西，你可以这样使用:(.|\n)*?

希望能有所帮助!

老实说，很多答案都是旧的，所以我发现，如果你只是简单地测试任何字符串，不管字符内容“/。*/i"将充分获得所有内容。
