you could do like this

on *:TEXT:*youtube.com/watch?v=*:#: {
  if (!$sock(youtube)) {
    noop $regex($strip($1-),http:\/\/.*youtube.*\/watch\?v=(.{11})&?.*)
    sockopen youtube www.youtube.com 80 | sockmark youtube $+(#,>,$regml(1))
    hmake ytb 10
  }
}

on *:SOCKOPEN:youtube: {
  sockwrite -n $sockname GET $+(/watch?v=,$gettok($sock(youtube).mark,2,62)) HTTP/1.0
  sockwrite -n $sockname Host: www.youtube.com
  sockwrite -n $sockname $crlf
}

on *:SOCKREAD:youtube: {
  var %ytx | sockread %ytx
  if $regex(%ytx,/<meta name="title" content="(.+)"/) { hadd ytb 1 1[1,0You0,4Tube] $qt($regml(1)) }
  if $regex(%ytx,/<strong>(\d+)<\/strong>/) { hadd ytb 2 Viewed: $regml(1) }
  if $regex(%ytx,/<a id="watch-username".*><strong>(.+)<\/strong><\/a>/) { hadd ytb 3 - User: $regml(1) }
  if $regex(%ytx,/<span class="likes">(\d+)<\/span>.*<span class="dislikes">(\d+)<\/span>/) { msg $gettok($sock($sockname).mark,1,62) $hget(ytb,1) - $hget(ytb,2) - $hget(ytb,3) - Likes: $regml(1) Dislikes: $regml(2) | sockclose $sockname | hfree ytb }
}

i created a hash to use it to put the data, so no need the sockclose event, by the way, it will return without the html tags, i just added a hmake on text event, and edited the entire sockread event, its just a tip test it

using this one the return will be this
