title: JQuery how to remove "id" from a part of html content
body: <p>I want to do something like this:</p>
  
  <pre><code>var html = $("#media").html();
  $("#multimedia-content").append(html);
  $("#multimedia-content").filter("*").removeAttr("id");
  </code></pre>
  
  <p>The 3th line fails, I want to remove all id's from this part of html but I don't know how to do the selection.</p>
  
  <p>Thanks!</p>
