looking for a pattern in ruby for matching string

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?

You want to use a non-greedy match, so change the regexp line to:

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