在红宝石中寻找匹配字符串的模式

Question

name="(this is 
a message
)

(other message)";

res=name.scan(/(\(.*\))/m);
puts res.join("###");

In the above code,I want to extract the matched parenthesis with the text inside the it as a whole expresstion.

I mean I want to get the following result through my code:

(this is 
a message
)###(other message)

That's to say,the length of the res should be 2 not 1, But in my code,I always get:

(this is 
a message
)
(other message)

There must be something wrong with my pattern,can any one help me to fix it?

您想要使用非贪婪的匹配，因此将正则表达式行更改为：

res=name.scan(/(\(.*?\))/m);
