title: jQuery: selectors with OR condition
body: <p>I've got following code:</p>
  
  <pre><code>$('table.tableElements thead|tbody tr').children().hover(function(){
      //    How can I do this ↑
  });
  </code></pre>
  
  <p>I'd like to catch all <code>tr's</code> of <code>thead</code> <b>OR</b> <code>tbody</code> but not <code>tfoot</code>.<br>
  How can I do this?</p>
