Match between two characters

Question

Is this possible?

From this string:

string = "lsdfh892pr23hr4342pr3j4r\n\nwww.foobar.com•\nyahoogooglebing"

I want to extract "www.foobar.com" .

And, from this one:

string = "lsdfh892pr23hr4342pr3j4r\n\ninfo@google.com•\nyahoogooglebing"

I want to extract "info@google.com" .

Answer 1

我不知道Ruby的语法，但是这个正则表达式应该工作：

/\n\n([^•]*)•/

Answer 2

I wouldn't bother with a regular expression:

string = "lsdfh892pr23hr4342pr3j4r\n\nwww.foobar.com•\nyahoogooglebing"
string.split("\n")[2][0..-2]
=> "www.foobar.com"

string = "lsdfh892pr23hr4342pr3j4r\n\ninfo@google.com•\nyahoogooglebing"
string.split("\n")[2][0..-2]
=> "info@google.com"
