Zend_Dom_Query to check schema.org markup

Question

I want to check if a website contains schema.org markup? I am doing the following:

$domain = 'http://agents.allstate.com/william-leahy-mount-prospect-il.html';            
$client = new Zend_Http_Client();
            $client->setUri($domain);
            $response = $client->request();
            $html = $response->getBody();
            $dom = new Zend_Dom_Query($html);
            $resultSchema = $dom->query('body');

            foreach($resultSchema as $r){
                $data = $r->hasAttribute('itemprop');
                if($data)
                    echo 'YEs';
                else 
                    echo 'No';
            }

I am not understanding how to find this. Is this the correct way of doing it? The schema.org markup used on the website may use any html element. How can i query all the elements and find one that contains the schema.org markup?

Finally after long search and reading was able to get the answer! This is how its done if someone's still looking for an answer.

$seperator = '|'; $dbData = '';
$domain = 'http://agents.allstate.com/william-leahy-mount-prospect-il.html';            
$client = new Zend_Http_Client();
$client->setUri($domain);
$response = $client->request();
$html = $response->getBody();
$dom = new Zend_Dom_Query($html);
$result = $dom->queryXpath('//*[@itemtype="http://schema.org/LocalBusiness"]');
            if($result->count()){
                foreach ($result as $r) {
                    if($r->hasChildnodes()) {
                        $lbHtml = $r->C14N();

                        $dom2 = new Zend_Dom_Query($lbHtml);
                        $lbname = $dom2->queryXpath('//*[@itemprop="name"]');
                        if($lbname->count()){
                            foreach ($lbname as $name) {
                                $name = $name->nodeValue;
                            }
                        }
                    }
                }
            }

            if(isset($name))
                $dbData .= 'name:'.$name.$seperator;
            else 
                $dbData .= 'name:'.$seperator;

            $result = $dom->queryXpath('//*[@itemtype="http://schema.org/PostalAddress"]');
            if($result->count()){
                foreach ($result as $r) {
                    $address = $r->nodeValue;
                }
            }

            if(isset($address))
                $dbData .= 'address:'.$address.$seperator;
            else
                $dbData .= 'address:'.$seperator;

            $result = $dom->queryXpath('//*[@itemprop="telephone"]');
            if($result->count()){
                foreach ($result as $r) {
                    $telephone = $r->nodeValue;
                }
            }

            if(isset($telephone))
                $dbData .= 'telephone:'.$telephone.$seperator;
            else
                $dbData .= 'telephone:'.$seperator;

            $dbData = trim($dbData,'|');

$dbData will contain string containing all the properties of the schema.org data. Hope it helps!
