How to validate different kind of a youtube link? for example: http://youtu.be/dQw4w9WgXcQ http://www.youtube.com/watch?v=dQw4w9WgXcQ http://www.youtube.com/?v=dQw4w9WgXckQ and convert this link to embed link like http://www.youtube.com/embed/dQw4w9WgXcQ to embed video in our application?

YouTube links can easily be matched with regular expressions. Check out this introduction to regular expressions if you’re not familiar with them yet: Regular Expressions Quick Start If you want to learn how to use regular expressions in Elixir, take a look at…

If the video IDs are guaranteed to be at the end, you can do a pattern match, which is probably a lot faster: def get_video_id("http://youtu.be/" <> id), do: id def get_video_id("http://www.youtube.com/watch?v=" <> id), do: id def get_video_id("http://www.youtube.com/?v=" <> id), do: id How you ca…

Also Erlang has a handy module http_uri , here’s how you use it case url |> String.to_char_list() |> :http_uri.parse() do {:ok, {scheme, user_info, host, port, path, query}} -> # check the host, extract id from query etc {:error, msg} -> # incorrect url - handle error end

It’s not quite the same: Note this function expects a well-formed URI and does not perform any validation. Erlangs function does perform validation and returns helpful messages, useful if these urls come from external source or user input.

You can’t expect YouTube URLs to have the id at the end since they can also take additional parameters.

Then an RegEx will be totally unreadable and absolutely not easy to get it right as well. Proper parsing of the URL is the only option then.

This is not a valid YouTube URL, by the way: http://www.youtube.com/?v=dQw4w9WgXckQ

[image] wmnnd: http://www.youtube.com/?v=dQw4w9WgXckQ But its one of the OPs examples, so he seems to allow it as a valid one… He must have got it from somewhere to list it up.

Can any one get me regEx to replace https://youtu.be/64XLNqIlY00 to https://www.youtube.com/watch?v=64XLNqIlY00??
