PHP for Breadcrumb

I need help with some php coding.

Current code:

if (is_category() || is_single() || is_archive()) {
	echo '<div itemscope itemtype="http://data-vocabulary.org/Breadcrumb">';
	the_category('title_li=');
	echo "</div> ";

Current output:

<div itemscope itemtype="http://data-vocabulary.org/Breadcrumb">
	<a href="http://www.nhpborneo.com/catalogue/insects" title="View all posts in Insects" rel="category tag">Insects</a>
</div>

I need help so that it outputs this instead:

<div itemscope itemtype="http://data-vocabulary.org/Breadcrumb">
	  <a href="http://www.nhpborneo.com/catalogue/insects" itemprop="url" title="View all posts in Insects" rel="category tag">
	  <span itemprop="title">Insects</span></a>
</div>
