You can't parse HTML with Regex. https://stackoverflow.com/questions/1732348/regex-match-open-tags-except-xhtml-self-contained-tags – Devin Dec 20 '17 at 09:13
use a DOM parser – Allan Dec 20 '17 at 09:15
please provide the rule you want to achieve in this searching text – karthik selvaraj Dec 20 '17 at 09:48
@karthikselvaraj I just to want to match text providing in question by regex providing in question, but i don't know why without g flag regex has match and with g flag not – O.Vykhor Dec 20 '17 at 09:52
@Oleksii - Sorry, what is meant by g flag. I could't understand – karthik selvaraj Dec 20 '17 at 10:02
@karthikselvaraj - This mean `/g` global searching, but i don't understand why not global searching has one match but global searching not. – O.Vykhor Dec 20 '17 at 10:03
@Oleksii Ruby regex does not use `g` flag. You need to use `String#scan(Regexp)` and make sure to use non-capturing groups, replace all `(` with `(?:`. – Wiktor Stribiżew Dec 20 '17 at 10:52
@WiktorStribiżew - why i should use non-capturing group? I want to use some value from searching text later. – O.Vykhor Dec 20 '17 at 10:59
ok, then just use `scan`. – Wiktor Stribiżew Dec 20 '17 at 11:05
@WiktorStribiżew thanks – O.Vykhor Dec 20 '17 at 11:26
