Help with Regex

[Eliran]

Hello

I am trying to get channels from this website:
www.afromotion.tv

I am using URL Helper to extract the .m3u url. However, they have wmsAuthSign= at the end meaning they expire after a couple of minutes. I am new to regex and I would like to learn how to use regex in order to update the parameters automatically and keep the channels more stable.

Can some provide me an example on what the regex url should look like with this channel?
http://www.afromotion.tv/afrotv/watch/D

Can someone please help?

Much appreciated!
