Diese Website ist nicht gut CSS-Selektoren hat, aber es ist noch nicht zu schwer, es mit XPath zu bekommen:

$dom = new DOMDocument(); 
@$dom->loadHTMLFile('http://www.hassconsult.co.ke/index.php?option=com_content&view=article&id=22&Itemid=29'); 
$xpath = new DOMXPath($dom); 

foreach($xpath->query("//div[@id='ad']/table") as $table) { 
    // title 
    echo $xpath->query(".//span[@class='style8']", $table)->item(0)->nodeValue . "\n"; 
    // price 
    echo $xpath->query(".//div[@class='style10']/div", $table)->item(0)->nodeValue . "\n"; 
    // description 
    echo $xpath->query(".//div[@align='justify']", $table)->item(0)->nodeValue . "\n"; 
}
