Regex to match anything after a delimiter

Question

I have the following case:

Time format and some description which is separated by a delimiter - (as like below)

00:00 - Hello element

I was using the below regex to detect the match

/((?:\d{2,}:)?(?:[0-5]\d):(?:[0-5]\d)(\s?-.\w+))/g;

it matches only "00:00 - Hello" after space it's not getting match. Here is the demo of it https://regex101.com/r/omUEHy/1

Also, If the string matches multiple times in a same line it should work.

If I have text like as 00:50 - Hello element 01:50 - Poetry. It should return 00:50 - Hello element and 01:50 - Poetry

Answer 1

The provided regex ... /\d{2}:\d{2}\s+.*?(?=\s+\d{2}:|\s+$)/g ... makes use of a positive lookahead ... (?=\s+\d{2}:|\s+$) (either whitespace sequence double digit and colon or whitespace sequence and end of string) ... in order to define the termination of the lazy/non greedy match of any character ... .*? ... which does follow the opening matching sequence of ... \d{2}:\d{2}\s+.

const multilineSample =
`00:50 - Hello element 01:50 - Poetry 00:50 - Hello element and another element    01:50 
- Poetry     00:50 - Hello element and another element    01:50 - Poetry  and prose 00:50 - Hello element   01:50   -   Poetry     `;

const regXTimeAndEntry = /\d{2}:\d{2}\s+.*?(?=\s+\d{2}:|\s+$)/g;

console.log(
  multilineSample.match(regXTimeAndEntry)
);
