title: jquery selector - selecting all span tags with id not equal to something
body: <p>I want to select all HTML <code>&lt;span&gt;</code> elements that don't have an <code>id</code> equal to <code>x</code> and hide them them.  Is this possible?  I think you have to use the <code>:not</code> selector but I can't work it out:</p>
  
  <p><code>$('span:not(#x').attr('style', "display: none;");</code></p>
  
  <p>Any ideas?  Thank you :).</p>
