with php? want convert bread crump structure in rdfa microdata. thank help

the solution regexp, works example code, when attribute order changes fails:

 $pattern = '#(?:rel\=\"v\:url\"\)? property\=\"v\:title\"\>([^\<]*)\<#ui';  $replacement = ' itemprop="url"><span itemprop="title">$1</span><';  $output = preg_replace($pattern,$replacement,$original); 

if possible, think of html/xml parsing when want manipulate html/xml source, here powerful tool: https://code.google.com/p/phpquery/. if use jquery js framework, tool easy ;) see:

require_once 'phpquery/phpquery.php'; $dom = phpquery::newdocument($original); foreach($dom->find('a[rel="v:url"]') &$item){     $txt = $this->text();     $item->        removeattr('rel')->        removeattr('property')->        attr('itemprop','url')->        html("<span itemprop=\"title\">$txt</span>");         } $output = "$original";
