AutoNav Breadcrumb Issue

Permalink
I am having an issue with autonav & breadcrumbs. No matter how I code I can't get it to do what I want. I want it to look like this

HOME // SUBPAGE // CURRENT PAGE

My current PHP theme for auto nav looks like

<?php  
   defined('C5_EXECUTE') or die(_("Access Denied."));
   $aBlocks = $controller->generateNav();
   $c = Page::getCurrentPage();
   $nh = Loader::helper('navigation');
   $i = 0;
   foreach($aBlocks as $ni) {
      $_c = $ni->getCollectionObject();
      if (!$_c->getCollectionAttributeValue('exclude_nav')) {   
         $pageLink = false;
         if ($_c->getCollectionAttributeValue('replace_link_with_first_in_nav')) {
            $subPage = $_c->getFirstChild();
            if ($subPage instanceof Page) {
               $pageLink = $nh->getLinkToCollection($subPage);
            }


Ideally I want the output code to appear as

<ul class="breadcrumbs">
    <li><a href="link">Home</a></li>
    <li><a href="link">Sub Page</a></li>
    <li><a href="link">Sub Page</a></li>
    <li class="current"><a href="link">Current Page</a></li>
</ul>


I am lost and need some help. Please

Thanks,
Andrew
