Hi.
I got a string:
"1|2 3 4 oh 5 oh oh|e eewrewr|7|".
I want to get the digits between first pipes (|), returning "2 3 4 5".
Can anyone help me with the regular expression to do that?

Does this work?
"1|2 3 4 oh 5 oh oh|e eewrewr|7|".split('|')[1].scan(/\d/)

...and to get numbers, instead of strings, you could append this: .map{|n| n.to_i}

... and to the numbers in one string as in your example, you append this instead: `.join(' ')`

@Nate: How about `.map!{|n| n.to_i}` (Personally, I like to mutate rather than get a new object)

"1|2 3 4 oh 54 5 oh oh|e eewrewr|7|" will return you: ["2", "3", "4", "5", "4", "5"]

Use this instead: "1|2 3 4 oh 55 oh oh|e eewrewr|7|".split('|')[1].scan(/\d+/)

A:
if you want to use just regex...
\|[\d\s\w]+\|
and then
\d
but that's probably not the best solution

Arun's answer is perfect if you want only digits. i.e.
"1|2 3 4 oh 5 oh oh|e eewrewr|7|".split('|')[1].scan(/\d/)
# Will return ["2", "3", "4", "5"]
"1|2 3 4 oh 55 oh oh|e eewrewr|7|".split('|')[1].scan(/\d/)
# Will return ["2", "3", "4", "5", "5"]
If you want numbers instead,
# Just adding a '+' in the regex:
"1|2 3 4 oh 55 oh oh|e eewrewr|7|".split('|')[1].scan(/\d+/)
# Will return ["2", "3", "4", "55"]
