Spry:repeat dataset in array

Question

I have a need to pass an indexed dataset to the 'spry:repeat' looping construct.  i.e.  if i have an array of datasets dsSource[0].. dsSource[n], stored in a standard JavaScript array, and I create an HTML construct such as:
<div class="TabbedPanelsContent attrList" spry:region="dsSource[0]">
  <table class="catTable">
    <tr>
      <th>Id</th>
      <th>Category</th>
    </tr>
    <tr spry:repeat="dsSource[0]">
      <td>
         {id}
      </td>
      <td>
         {category}
          </td>
    </tr>
  </table>
</div>
This does not appear to be parsed correctly by Spry.  I get a 'Failed to retrieve data set (dsSource[0]) for spry:repeat' message.  How do I get Spry to use a dataset from an array, here?

I got help from V1 Fusion on something like this today. Try
creating a div with the dsPhoto region then have a div with the
spry:repeat of the dsPhoto then inside that have a span that uses
the spry:if to call the function and check if something is
returned.
Something like this:
&lt;html&gt;
&lt;head&gt;
&lt;script language=&quot;JavaScript&quot;
type=&quot;text/javascript&quot;
src=&quot;includes/xpath.js&quot;&gt;&lt;/script&gt;
&lt;script language=&quot;JavaScript&quot;
type=&quot;text/javascript&quot;
src=&quot;includes/SpryData.js&quot;&gt;&lt;/script&gt;
&lt;script type=&quot;text/javascript&quot;
src=&quot;
http://slideshow.triptracker.net/slide.js&quot;&gt;&lt;/script&gt;
&lt;script language=&quot;JavaScript&quot;
type=&quot;text/javascript&quot;&gt;
&lt;!--
dsPhoto = new
Spry.Data.XMLDataSet(&quot;photos.xml&quot;,&quot;gallery/photo&quot;);
var viewer = new PhotoViewer();
//--&gt;
&lt;/script&gt;
&lt;/head&gt;
&lt;body&gt;
&lt;div spry:region=&quot;dsPhoto&quot;&gt;
&lt;div spry:repeat=&quot;dsPhoto&quot;&gt;
&lt;span spry:if=&quot;viewer.add('/photos/{path}')
!= 0&quot;&gt;&lt;/span&gt;
&lt;/div&gt;
&lt;/div&gt;
&lt;a
href=&quot;javascript:void(viewer.show(0))&quot;&gt;Slideshow&lt;/a&gt;
&lt;/body&gt;
&lt;/html&gt;
