Detect Complex Dice Formats

I am currently working on a program that scans a page and highlights dice rolls and then lets you click to rolls those dice.

The program mostly works as expected, for example if the page contains stuff like 1d6, 1d6 + 3, d20, or 1d6 x 100 it picks up and rolls it. However I would like the ability to detect more complicated roles for example 1d20 + 4 1d12 + 12 and then parse that out into its individual roles. I would like to avoid detecting things like 1d20 + 4 the 1d12 + 12, basically, avoid things that have words instead of spaces in the dice roll.

1d6

1d6 + 3

d20

1d6 x 100

1d20 + 4 1d12 + 12

1d20 + 4 the 1d12 + 12

My script uses regex to match patterns on the page and highlight them. I am not sure if this is something I could add to my regex since this is really been my project for learning regex. Here is the current regex I am using

([+−-]d+)|(([1-9]d*)?d([1-9]d*)s*([+-−]s*d+)?([,]s*d+)?)

([+−-]d+)|(([1-9]d*)?d([1-9]d*)s*([+-−]s*d+)?([,]s*d+)?)

I think this is what you want

((?:[+-]?[1-9]d*)?d[1-9]d*(?:s+[-+x]s+[1-9]d*)?(?:s+(?:[+-]?[1-9]d*)?d[1-9]d*(?:s+[+-x]s+[1-9]d*))*)

((?:[+-]?[1-9]d*)?d[1-9]d*(?:s+[-+x]s+[1-9]d*)?(?:s+(?:[+-]?[1-9]d*)?d[1-9]d*(?:s+[+-x]s+[1-9]d*))*)
