Regular expression for URL which not containing youtube

I want to create a regular expresion which match with an URL except URl containing "youtube".

I have done this regexp which match with all URL:

(www+\.)?[\w-]+s{0,3}[/\.,;:!]{1,3}\s{0,3}(r[o0]|n[e3]t|lt|c[o0]m|[i!]nf[o0]|[o0]rg|b[i!][z2]|ru|[e3]du)(\/)?

But i want to add in the regular expresion, to not match if the URL containing 'youtube'.

We have a big system wich filter sentences that we received, and for each sentences received, we apply several regular expressions for example. And i want a regular expresion which say, this sentence containing an URL but not containing "youtube".

Is it possible?

Thanks

I would do this :

Regex

(www+\.)?(?!youtube)([\w-]+s{0,3})[/\.,;:!]{1,3}\s{0,3}(r[o0]|n[e3]t|lt|c[o0]m|[i!]nf[o0]|[o0]rg|b[i!][z2]|ru|[e3]du)(\/)?

Test

youtube.com            => No Match
test.n3t               => Match
wwwwwww.coucous::.3du  => Match
utube;;; r0            => Match

here is the good example of "Regex match all url except youtube ones"

https://stackoverflow.com/a/6681321/2413470

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

Don't use a regex for this, use URI:

final URI uri = new URI(inputString);

// test against this URI's `.getHost()`, or `.getPath()`; whatever is relevant

Imprint this into your head using red iron/nitric acid(1): every time you have to do content checking of a URL or any URI in pure Java, use URI. Not regexes. URI will parse the thing for you.

Oh, and another thing: unlike URL, when compared with .equals(), URI will not attempt to resolve the hostname. This is no joke. Using URLs as keys into a map, or members of a set, is asking for trouble... Fortunately, URL has a .toURI() method.
