Zend_Navigation: How to add numberings in the menu items? - zend-framework

Question

I am generating XML from database records, then feeding it to Zend_Navigation to render it as treeview and before rendering I would like to add the level numbers, like a TOC numberings:
I have:
$partial = array('partials/menu.phtml', 'default');
$this->navigation()->menu()->setPartial($partial);
echo $this->navigation()->menu()->setUlClass('treeview')->render();
The output is dressed with ul/li(I need ul for treeview):
My First Web Page
Nice Page
Main Help
Works
But I Need:
1.My First Web Page
1.1 Nice Page
1.1.1 Main Help
1.2 Works
How can I dress each level with a number?
$navarray=$this->navigation()->menu()->toArray();
$it = new RecursiveIteratorIterator(new RecursiveArrayIterator($navarray[0]), RecursiveIteratorIterator::SELF_FIRST);
foreach ($it as $row) {
/// ????
}
Thanks Arman.

Maybe you could modify the partial to render an ol instead of ul, and then use some CSS magic to render the numbering properly.
You can see the example #48 in the Menu Helper documentation to get some inspiration.
EDIT:
If you need to use the ul tag, then probably you'll need to add the "current depth" of the menu items by hand. There is a very similar question answered here: PHP RecursiveIteratorIterator: Determining first and last item at each branch level.
Hope that helps,
