Does your code work alright? -> No - ask a question on SO. Yes, but I want to enhance it -> ask at Code Review. — Wiktor Stribiżew

val url = "bla_bla/5555/review"
val pattern = "[0-9]+".r

To find a single match, you can do

pattern.findFirstMatchIn(url)

For more than one match, you can do

 pattern.findAllMatchIn(url)
