Regex match all url except youtube ones

问题

I am sure this is a trivial questions for you genii here. I seem to be stuck

I have a couple of links to process and I want to convert all links to hyperlinks and youtube links to youtube videos.

I have everything working. I just need to figure out how to regex out all links EXCEPT youtube ones.

Here is an example of my regex: http://gskinner.com/RegExr/?2u7g4

thanks.

Help please.

I would use the regex:

/(http:\/\/)?(www\.)?youtube.com\S*/

to match youtube links. Or did you mean you wanted to add on top of the regex you already have?

Edit: Oh, I'm dumb and wrote something super long, yeah, just negative lookahead at the beginning of your match:

(?!\S+youtube\.com)((?<!\S)(((f|ht){1}tp[s]?:\/\/|(?<!\S)www\.)[-a-zA-Z0-9@:%_\+.~#?&\/\/=]+))
