java test string

quote text

Match a html tag.

sdfsdfsdfsdf

in this one you should find a repeating sequence inside the substring. I have an example for you: in a string "abababc" - "ab" is a sequence that repeats more than once, so the answer will be "ababab" `repeat_inside('aaaaa') == 'aaaaa' repeat_inside('aabbff') == 'aa' repeat_inside('aababcc'...

Parses ISO date like: 2021-01-19T15:21:32.59+02:00 and returns these named groups: fulldate (full date and time) date (2021-01-19)...
