Question

I am trying to extract the video id from a youtube url using the following:

val YoutubeRegex = """v=([^&]+)""".r

  "v=IQJ13vFYOU8&feature=g-all-lik" match {
    case YoutubeRegex(videoId) => videoId
    case _ => throw new NoSuchFieldError("impossible to find youtube Id")
  }

Saddly this does not work … Any ideas ? Thanks a lot

Answer 1

Isn’t that supposed to be like that?

val YoutubeRegex = """v=([^&]+).*""".r // need to specify that there could be remainder

"v=IQJ13vFYOU8&feature=g-all-lik" match {
  case YoutubeRegex(videoId) => videoId
  case _ => throw new NoSuchFieldError("impossible to find youtube Id")
}

So you will get IQJ13vFYOU8 part without options.
