Same situation as before.
You sent some examples, you got answer.
Now you came that it doesn't match something totaly different.

Learn about regular examples, build your expression part by part to match your URLs.
First you need to uderstand, how it works. Without it, you will stay copy/paste guy only

This regex is good for MULTIPLE URLs, but it [b]still needs to be correct: "-" and "/"
number/number/number/number
OR
number/number/number-number

\.ru/([^/]+)/([^/]+)/(\-*\d+)|\.ru/avtor+/[a-zA-Z0-9-]+$

probably need to use

\b

The metacharacter \b is an anchor like the caret and the dollar sign. It matches at a position that is called a “word boundary”. This match is zero-length.

pspad:
\.ru/([^/]+)/([^/]+)/(\-*\d+)

Wrong Match!

Again!
Must Match
XXX/XXX/XXX-XXX
and
Must Match
XXX/XXX/XXX/XXX

Invalid regex / Not extract url:

\.ru/([^/]+)/([^/]+)/(\-*\d+)|\.ru/avtor+(/[a-zA-Z0-9-]+)+$

shoulbe detect match:
.ru/avtor/1gG-

Ignore \s (url match)

pspad:
\.ru(/[a-zA-Z0-9-]+)+

Work.

But first regex still does not detect the full address

\.ru/([^/]+)/([^/]+)/(\d+\-*\d+)

.ru/2098/333/333/456

So you have regular expression what detects first part correctly and you have expression what works correctly with the rest of address.
Put them together. But to do it you need to understand what you are doing.

The expression works, but it's messy!
Here practically "|" is unnecessary but I can't correct the last part to match for "XXX-XXX" and "XXX/XXX"

\.ru/([^/]+)/([^/]+)/([^/]+)/(\d+)|\.ru/([^/]+)/([^/]+)/(\d+-\d+)|\.ru/avtor(/[a-zA-Z0-9-]+)+
