Regex, match with different patterns at once

I have a giant string with this format:

5 [105.68 - 143.759] some text
6 [143.759 - 173.88] some text
7 [173.88 - 201.839] some text
...

I want to match:

1. Numbers including the dot between [ and -, this is the regex: /(?<=\[).*?(?=\ )/
2. Numbers including the dot between - and ], this is the regex: /(?<=\-\ ).*?(?=\])/
3. All text after ] , for this I use this regex: /(?<=\]\ ).*/

So for example for the first line the matches will be: 105.68, 143.759 and some text

This works but I want to know if is possible to match those three patterns at once, I tried concatenating the different patterns with | but it didn’t work with this:

const re = /(?<=\[).*?(?=\ )|(?<=\-\ ).*?(?=\])|(?<=\-\ ).*?(?=\])/
const regex = RegExp(re, 'gm')
regex.exec("7 [173.88 - 201.839] some text")

Output 1st time calling exec: Array [ "201.839" ]
Output 2nd time calling exec: Array [ "173.88" ]
Output 3rd time calling exec: null

Is there a way to get all this (and the actual text, not null) in a single call?

>Solution :

You could use match() with three capture groups:

var input = "5 [105.68 - 143.759] some text";
var matches = input.match(/\[(\d+(?:\.\d+)?)\s*-\s*(\d+(?:\.\d+)?)\]\s+(.*)/);
console.log("1st num: " + matches[1]);
console.log("2nd num: " + matches[2]);
console.log("text:    " + matches[3]);

If you need to apply this to a multiline string, then you could split the string by space and then apply the above to each line.
