Regex optionally extracting characters between two characters

Question

I have the following string thisIs/My-7777-Any-other-text it also is possible for the following thisIs/My-7777

I am looking to extract My-777 in both scenarios using regex. So essentially I am looking to extract everything between the first forward flash and the second hyphen (Second hyphen may not exist). I tried the following regex which wasn't quite right

(?<=/)(.*)(?=-)

Answer 1

You could use a capture group

^[^/]*/([^-]*-[^-]*)

• ^ Start of string
• [^/]*/
• ( Capture group
  • [^-]*-[^-]* Match a - between optional chars that are not -
• ) Close capture group

Without an anchor, and not allowing / before and after -

[^/]*/([^-/]*-[^-/]*)
