title: E4X: Insert nodes in XMLList for missing date?
body: <p>if I have an XML object like this:</p>
  
  <pre><code>    &lt;a&gt;
      &lt;u date="2009-04-10" value="543"/&gt;
      &lt;u date="2009-04-11" value="234"/&gt;
      &lt;u date="2009-04-13" value="321"/&gt;
      &lt;u date="2009-04-14" value="66"/&gt;
      &lt;u date="2009-04-16" value="234"/&gt;
  
      &lt;t date="2009-04-01" value="43"/&gt;
      &lt;t date="2009-04-02" value="67"/&gt;
      &lt;t date="2009-04-03" value="432"/&gt;
      &lt;t date="2009-04-08" value="123"/&gt;
      &lt;t date="2009-04-09" value="65"/&gt;
  
      &lt;l date="2009-04-01" value="12"/&gt;
      &lt;l date="2009-04-02" value="76"/&gt;
      &lt;l date="2009-04-03" value="123"/&gt;
      &lt;l date="2009-04-04" value="6543"/&gt;
      &lt;l date="2009-04-05" value="123"/&gt;
      &lt;l date="2009-04-06" value="65"/&gt;
      &lt;l date="2009-04-15" value="234"/&gt;
      &lt;l date="2009-04-16" value="65"/&gt;
  &lt;/a&gt;
  </code></pre>
  
  <p>There is 3 XMLLists in this XML object. If you notice, the dates have gaps in them. Is there a way to add the missing dates to each XMLList? With a value of 0.</p>
  
  <p>Also I do not want to add any dates before or after the first and last node in each XMLList...i just want to fill in the missing dates between each node.</p>
  
  <p>How can I do that?</p>
  
  <p>Thanks!!!</p>
