title: Showing a loader while Spry XMLDataset loads the data
body: <p>I am using Spry (<code>SpryData.js,xpath.js</code>)</p>
  
  <pre><code>    var ds1 = new Spry.Data.XMLDataSet("_db/db.xml", "bildiriler/bildiri",{useCache:false});
   // load the xml tree
  </code></pre>
  
  <p>....</p>
  
  <pre><code>&lt;!-- use it in a loop - 
   Sometimes the page use "ds1.loadData();" to refresh the data --&gt;
   &lt;div spry:region="ds1" spry:repeatchildren="ds1"&gt;
   &lt;a href="#"&gt;{author}&lt;/a&gt;&lt;/div&gt;
  </code></pre>
  
  <p>So how can I show a loader animation or "Loading text" while XML data is loading </p>
  
  <p>(It takes a long time -about 2 sec from a slow CD-. My XML file is big 100KB )</p>
