title: Filter and sort XML before binding it to a repeater?
body: <p>How I can filter, sort xml before binding it to a repeater?
  I have a xml data which I need to filter on the basis of querystring and then sort it before binding it into repeater.</p>
  
  <p>I know how to bind xml with repeater and its working fine too but I am facing problem in filtering based on query string and sorting.</p>
  
  <p>Any help would really be appreciated?</p>
  
  <p>My XML is like this</p>
  
  <pre><code>&lt;Categories&gt;   
      &lt;Category&gt;
          &lt;Title&gt;Food&lt;Title&gt;
          &lt;Date&gt;12/1/2009&lt;/Date&gt;
          &lt;Duration&gt;12/1/2009-12/1/2011&lt;/Duration&gt;
          &lt;Description&gt;Who is hungry&lt;/Description&gt;
       &lt;Category&gt;
  &lt;Categories&gt;
  </code></pre>
  
  <p>I want to sort by date and duration. I also want to filter by title (based on the querystring).</p>
