Flashing title shows HTML

When I have a guest and that guest posts something, the title start flashing. Up to here, nothing wrong.

However, that guest name is something like this:

Alexis <div class="guest-user">guest-123</div>

I don't remember the exact class name, but that's something like this.

We could handle that problem in the JavaScript so it is done on the client's machine! (and that way we save cycles on the server)

  document.title = Drupal.settings.chatroom.newMsg.name + ' says: ' + Drupal.settings.chatroom.newMsg.text;

I think that all we need to do is use the name up to the first '<'... Something like this (NOT TESTED!):

  var name = Drupal.settings.chatroom.newMsg.name;
  var p = name.find('<');
  if(p) {
    name = name.substr(0, p);
  }
  document.title = name + ' says: ' + Drupal.settings.chatroom.newMsg.text;

Thank you.
Alexis
