Question

This should be simple but i cant seem to get it going. The purpose of it is to extract v3 tags from mp3 file names in Mp3tag.

I have these strings I want to extract the year.

Test String 1 (1994) -> extract 1994
34 Test String 2 (1995)" -> extract 1995
Test (String) 3 (1996)" -> extract 1996

I had ^(.+)\s\(([0-9]*)\)$ but obviously its not giving me the results i was expecting. You can say that im not very good with regular expressions.

Thanks in advance

Answer 1

You can use something like this \((\d{4})\)$. The first group will have your match.

Explanation

\(       # Match the character “(” literally
(        # Match the regular expression below and capture its match into backreference number 1
   \d       # Match a single digit 0..9
      {4}      # Exactly 4 times
)
\)       # Match the character “)” literally
$        # Assert position at the end of a line (at the end of the string or before a line break character)
