(.*) captures all string before ([0-9 ]+) how can i prevent it from capturing (?<=season ) which is before ([0-9 ]+).
P.S i cant just negate "season" from (.*) . i.e tv game of season season 1 2 3 should capture tv game of season 1 2 3
You can use
^(movie|tv)\s*(.*?)(?:\s+season)?(?:\s+([0-9]+(?:\s+[0-9]+)*))?$
See the regex demo.
