To sum up the Regular expression that matches the requirements is:

https?:\/\/(?:w{1,3}\.)?[^\s.]+(?:\.[a-z]+)*(?::\d+)?((?:\/\w+)|(?:-\w+))*\/?(?![^<]*(?:<\/\w+>|\/?>))

This expression includes the following characters in the url:

  • '/'
  • '-'
  • '_'

There are a few things to note in the pattern.

You have to escape the dot to match it literally in this part (?:w{1,3}\.)?

If you add the dot to the character class [^\s.]* you don't have to make it a non greedy quantifier.

You can omit the outer capturing group if you want the match only.

You could make the port part optional (?::\d+)? to match it:

https?:\/\/(?:w{1,3}\.)?[^\s.]+(?:\.[a-z]+)*(?::\d+)?(?![^<]*(?:<\/\w+>|\/?>))
