[YouTube-API] Re: Strip away video url leaving only the video ID using Java Regular expressions?

Hello Miguel,

We don't make any guarantees about our URL formats for watch pages.
They're not part of any supported API, and they might change or new
formats for the URL might roll out at any time.

That being said, most watch page URLs nowadays have a v=VIDEO_ID URL
query parameter in them, and the easiest way to parse that would
probably just to use a URL parser that will tokenize the URL's query
parameters properly and check for the value of the "v" parameter.
Here's a page dedicated to a discussion of parsing URL query
parameters from Java:

http://stackoverflow.com/questions/1667278/parsing-query-strings-in-java

If you want a regex, /[?&;]v=([^?&;]+)/ would probably be my
recommendation, though I'm sure you could do better. Again, this
depends on the video id being in the v= URL parameter, which I can't
guarantee will always be the case for all URLs.
