Is it possible to exclude only query parameters from the URL string using regular expressions while leaving hash?

For example, if there is a URL like this
https://www.example.com/test/?q=test&s=test
https://www.example.com/hoge/?q=foo&s=faa#hoge

I would like to exclude only query parameters and extract the following URL and hash.
https://www.example.com/test/
https://www.example.com/hoge/#hoge

Is it possible to do this in a regular expression?
I would appreciate your advice.

With this property, regular expression replacement will be easy to achieve.For example,

^([^?)#]*)(\?[^#]*)?(#.*)?$

If you leave the first and third groups in this regular expression, it will be the desired behavior.

RFC 3986 contains the regular expression for the URI.I think it will be helpful.

^([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\?([^#]*))?(#(.*))?
       12            3  4          5       6  7        8 9

Also, some programming languages have libraries that express URLs/URIs, so using them may be easier to understand than using regular expressions.
