RegEx for segmenting a string

Question

I found this Answer for how to paras movie names with RegExp, its working fine but not exactly what i need.

The input string is : 2001.A.Space.Odyssey.1968.720p.BluRay.DD5.1.x264-LiNG.mkv

The Regular Expression that used in the answer like this :^(.+).(\d{4}).+.(mp4|avi|mkv)$ and the output is:

2001.A.Space.Odyssey
1968
mkv 

What i need is like the below :

2001.A.Space.Odyssey
1968
LiNG
mkv 

My try was: ^(.+).(\d{4}).+([^_]).(mp4|avi|mkv)$ but the output is:

2001.A.Space.Odyssey
1968
G
mkv 

How i can get LiNG instead of G ?

Answer 1

This expression has four capturing groups:

(.+?)\.([0-9]{4}).+?-(.+)\.(mkv|avi|mp4)

where our desired outputs are.

The name of the movie is in the first capturing group:

(.+?)

followed by a . and the desired year in the second group:

([0-9]{4})

followed by everything else upto the last dash and here we are having the last word:

(.+)

and the desired extensions are in the last capturing group:

(mkv|avi|mp4)

DEMO

Test

const regex = /(.+?)\.([0-9]{4}).+?-(.+)\.(mkv|avi|mp4)/;
const str = `2001.A.Space.Odyssey.1968.720p.BluRay.DD5.1.x264-LiNG.mkv`;
const subst = `$1\n$2\n$3\n$4`;

// The substituted value will be contained in the result variable
const result = str.replace(regex, subst);

console.log('Substitution result: ', result);
