Find all links with specific domain in the text with regex

I have a text with links inside, so I try to match them with regex, but somehow the last step I miss..

Link to regex – https://regex101.com/r/pXzZvA/1

The text:

Some text with many letters and some kind of bla bla text
With links - -https://sub.mydomain.com/products/art-for-selling-1   - another word

-https://sub.mydomain.com/products/art-for-selling-1 
https://sub.mydomain.com/products/art-for-selling-1 

paf paf

pew pew 

sub.mydomain.com/products/art-for-selling-1

Here is the regex I use:

/(?:https?:\/\/)?(?:[^\.]+\.)?sub.mydomain.com(\/.*)$/gm

What do I miss is with all the matches I have match of "https://sub.mydomain.com/products/art-for-selling-1 – another word" with " – another word" together. I need to add space exclusion to the end of the regex.

>Solution :

use: (?:https?:\/\/)?(?:\w+\.)?sub\.mydomain\.com\/(?:\w+-?\/?)+

(?:https?:\/\/) : contain https:// or not (http or https)

(?:\w+\.)? : contain a word follow by . or not

sub\.mydomain\.com\/ : must contain sub.mydomain.com/

(?:\w+-?\/?)+ : contain many forms of abc/abc/abc/.../... or not (and may be contained a - after the word or not)
