XML Nested Structure

Question

Hello,
I am building menu menu from the xml file using Spry Widget.
My XML structure is
main id="002">
<title>Payment Reports</title>
<link>#</link>
<submenu id="21">
<linkinner>/lckbx/main/payment_default</linkinner>
<titleinner>Check Payment Report</titleinner>
</submenu>
<submenu id="22">
<linkinner>/lckbx/main/postedpayment_default</linkinner>
<titleinner>Posted Payment Report</titleinner>
</submenu>
</main>
My nested xml calls are
var dsItems = new
Spry.Data.XMLDataSet("/menu/lockbox_menu.xml", "/buildmenu/main");
// Setup a couple of nested data sets:
var subItems = new Spry.Data.NestedXMLDataSet(dsItems,
"submenu/titleinner", "submenu/linkinner");
My problem is I am not be able to access the value of
"submenu/linkinner" from the xml file.
<li spry:repeat="subItems"
title="{subItems::titleinner}"><a
href="{subItems::linkinner}">{subItems::titleinner}</a></li>
I can not either create and use the thrid dataset as nested
data regions are not allowed if I create a third data set then they
over laps.
I can only fetch the value from the first element of the
nested structure. Please help me out how to fetch value from the
second sub value from nested tag.
Thank you,
Kamal.

Kamal,
The problem lies in your constructor for the
nestedXMLDataSet. That constructor should have only two arguments
(it can have optional arguements as well, but it's not necessary to
go into those to solve your issue). The two arguments for the
nestedXMLDataSet constructor should be, the previously defined
DataSet and the xPath for the nested data.
You could solve this a couple ways. This would be a way to do
it without changing your XML file (or much else) -- change your
nestedXMLDataSet constructor to provide only one xPath argument at
the "submenu" level of your XML doc:
<script type="text/javascript">
<!--//
var dsItems = new
Spry.Data.XMLDataSet("/menu/lockbox_menu.xml", "/buildmenu/main");
var subItems = new Spry.Data.NestedXMLDataSet(dsItems,
"submenu");
//-->
</script>
For your nestedXMLDataSet, you need only go one level further
(beyond the level indicated in the dsItems dataSet) to get to the
data you want. The <linkinner> and <titleinner> tags
are both child nodes nested at the same level below the
<submenu> node of your XML doc, so you can access them then
(when your nested set is simply "submenu") by the tag names, as in:
{subItems::linkinner}
Accessing them in your page body would look like this:
<div spry:region="dsItems subItems">
<ul>
<li spry:repeat="subItems"
title="{subItems::titleinner}"><a
href="{subItems::linkinner}">{subItems::titleinner}</a></li>
</ul>
</div>
For the spry:region, reference the primary dataSet (dsItems)
as well as the nested set (subItems), and then the rest of it for
the list item is the same as what you already listed in your post.
