Question

I have html like this

<iframe width="560" height="315" src="http://www.youtube.com/embed/Wa6CA3YqV2Q" frameborder="0" allowfullscreen></iframe>

How do i get video id Wa6CA3YqV2Q with regex? And are there any other ways to achieve this?

UPD: I have used Nokogiri, and i managed to get http://www.youtube.com/embed/Wa6CA3YqV2Q, so how do i get id, of video having this link?

The code below will take any vimeo or youtube URL and return the video ID and the provider.

In your model

def parse_video_url(url)
    @url = url

    youtube_formats = [
        %r(https?://youtu\.be/(.+)),
        %r(https?://www\.youtube\.com/watch\?v=(.*?)(&|#|$)),
        %r(https?://www\.youtube\.com/embed/(.*?)(\?|$)),
        %r(https?://www\.youtube\.com/v/(.*?)(#|\?|$)),
        %r(https?://www\.youtube\.com/user/.*?#\w/\w/\w/\w/(.+)\b)
      ]

    vimeo_formats = [%r(https?://vimeo.com\/(\d+)), %r(https?:\/\/(www\.)?vimeo.com\/(\d+))]  

    @url.strip!

    if @url.include? "youtu"
      youtube_formats.find { |format| @url =~ format } and $1
      @results = {provider: "youtube", id: $1}
      @results
    elsif @url.include? "vimeo"  
      vimeo_formats.find { |format| @url =~ format } and $1
      @results = {provider: "vimeo", id: $1}
      @results
    else
      return nil # There should probably be some error message here
    end  
end

Then in your controller just call:

@results = @course.parse_video_url(@course.video_url)
# Access the hash with @results[:provider] or @results [:id]

And in your view you can write an IF statement to display the relevant embed code for the provider/id combo.

Ended with following

string = 'http://www.youtube.com/embed/Wa6CA3YqV2Q'

result =  string.split('/').last

you can use

string.scan(/src="\S+\/(\w+)"/)[0][0]

but if you're doing a lot of html work i would recommend using a full-on HTML parser like Nokogiri or something perhaps more lightweight.

While you might be able to parse it with a regex, parsing arbitrary html with regexs is bad unless you really know what you're doing. There's a lot of historical controversy around the subject, search about it if you're interested.

The proper way is to parse the document, there's a great parser for rails:

used nokogiri, got link, now need to get all symbols after last `/` – Avdept Jun 14 '13 at 07:53
Because Youtube urls can vary a lot, this is not an easy one. Check other answered questions like: http://stackoverflow.com/questions/2936467/parse-youtube-video-id-using-preg-match/6382259#6382259 http://stackoverflow.com/questions/6556772/parsing-youtube-url – bluehallu Jun 14 '13 at 07:56

Try this:

string = 'http://www.youtube.com/embed/Wa6CA3YqV2Q'
regex = /^(?:https?:\/\/)?(?:www\.)?\w*\.\w*\/(?:watch\?v=)?((?:p\/)?[\w\-]+)/
match = string.match(regex)
if match
  return match[1]
end
return ''

I got it from here and changed it a little bit: Parsing youtube url
