Regex to match Youtube URLs (using Ruby)

I created a regular expression in order to match Youtube URLs.

Currently, the most common URLs from Youtube are http://youtube.com and http://youtu.be:

/(?:https?:\/\/)?(?:www\.)?youtu(?:\.be|be\.com)\/(?:watch\?v=)?(\w{10,})/

This regex will match:

http://youtube.com/watch?v=1234567890
https://youtube.com/watch?v=1234567890
http://www.youtube.com/watch?v=1234567890
https://www.youtube.com/watch?v=1234567890
http://youtu.be/1234567890
https://youtu.be/1234567890

www.youtube.com/watch?v=1234567890
youtube.com/watch?v=1234567890
youtu.be/1234567890

And won’t match:

Então… acho que tem um validador do próprio youtube, você passa a URL e ele valida :-)

Hum, interessante. Tem o link?

Acho que da pra você trocar ‘(?:s?)’ por ‘s?’

Verdade! Vou trocar! Thanks!
