Nested XML & Pagination

Question

Hi,
Just wondering if anyone has implemented pagination for
nested XML. Our XML structure is as following:
<items>
<item id="0001" type="donut">
<name>Cake</name>
<ppu>0.55</ppu>
<batters>
<batter id="1001">Regular</batter>
<batter id="1002">Chocolate</batter>
<batter id="1003">Blueberry</batter>
</batters>
<topping id="5001">None</topping>
<topping id="5002">Glazed</topping>
<topping id="5005">Sugar</topping>
<topping id="5006">Sprinkles</topping>
<topping id="5003">Chocolate</topping>
<topping id="5004">Maple</topping>
</item>
</items>
We are trying to achieve the following display:
* Cake
o None
o Glazed
o Sugar
o Powdered Sugar
o Chocolate with Sprinkles
o Chocolate
o Maple
* Raised
o None
o Glazed
o Sugar
o Chocolate
o Maple
* Buttermilk
* Bar
o Chocolate
o Maple
* Twist
o Glazed
o Sugar
* Filled
o Glazed
o Powdered Sugar
o Chocolate
o Maple
The Spry code for it as following:
<script language="JavaScript" type="text/javascript"
src="../../includes/xpath.js"></script>
<script language="JavaScript" type="text/javascript"
src="../../includes/SpryData.js"></script>
<script language="JavaScript" type="text/javascript"
src="../../includes/SpryNestedXMLDataSet.js"></script>
<script type="text/javascript">
// Setup a parent data set:
var dsItems1 = new
Spry.Data.XMLDataSet("../../data/donuts.xml", "/items/item");
// Setup a couple of nested data sets:
var dsBatters = new Spry.Data.NestedXMLDataSet(dsItems1,
"batters/batter");
var dsToppings = new Spry.Data.NestedXMLDataSet(dsItems1,
"topping");
</script>
<div spry:region="dsItems1 dsToppings">
<ul>
<li spry:repeat="dsItems1">{dsItems1::name}
<ul>
<li
spry:repeat="dsToppings">{dsToppings::topping}</li>
</ul>
</li>
</ul>
</div>
We want to implement pagination on dsItems1::name. Any help
on how to implement pagination on it would be greatly appreciated.
Many thanks.
Cheers,
D.

Hi DharmenderY,
The PagedView data set doesn't work very well with Nested
Data Sets. This is something I want to fix in the next version. The
work around is to make nested data sets based on the paged view:
// Setup a parent data set:
var dsItems1 = new
Spry.Data.XMLDataSet("../../data/donuts.xml", "/items/item");
var pvItems1 = new Spry.Data.PagedView(dsItems1);
// Setup a couple of nested data sets:
var dsBatters = new Spry.Data.NestedXMLDataSet(pvItems1,
"batters/batter");
var dsToppings = new Spry.Data.NestedXMLDataSet(pvItems1,
"topping");
That should get things rendering properly.
