Ruby regex not ignoring whitespace

Question

Matching S01E01 in Ruby

with

/S\d+?E\d+?/ix

which works, however, S01 E01 does not. I thought the /x should ignore white spaces?

Answer 1

/x ignores whitespace inside your regex, not in the text you're matching.

You're looking for

/S\d+?\s*E\d+?/i
