use DOMElement::getAttribute

$art->getAttribute('class');

also, simpleHTMLDOM is more suitable for dealing with html:

$html = str_get_html($page);
foreach($html->find('td') as $element) 
   echo $element->class.'<br>';
}

Care to elaborate why SimpleHtmlDom is "more suitable" than DOM for dealing with HTML? DOM handles HTML fine.

DOMXPath's query function returns a DOMNodeList, ~~which (I'm pretty sure) cannot be used in a foreach($ARRAY) loop~~ [Edit: it can]. ~~You'll have to implement a modified for loop in order to read the DOMNode elements inside the list class:~~ [Edit: not necessary; see below]

foreach ($arts as $art) {
     # code-hardiness checking
     if ($art && $art->hasAttributes()) {
         # (note: chaining will only work in PHP 5+)
         $class = $art->attributes->getNamedItem('class');
         print($class . "\n");
     }
}

thanks for the info. just so you'll know, it does support foreach :)

Class [ <internal:dom> <iterateable> class DOMNodeList ] which means it can be used in a foreach construct

<td> is a DOMElement (not just a DOMNode), so $art->getAttribute('class') would suffice.
