将HTML解析为数组

Question

I have an array that is being returned from a rss feed.

$rss = new DOMDocument();
    $rss->load('http://www.rssfeed');
    $feed = array();
    foreach ($rss->getElementsByTagName('item') as $node) {
        $item = array ( 
            'title' => $node->getElementsByTagName('title')->item(0)->nodeValue,
            'desc' => $node->getElementsByTagName('description')->item(0)->nodeValue,
            'link' => $node->getElementsByTagName('link')->item(0)->nodeValue,
            'date' => $node->getElementsByTagName('pubDate')->item(0)->nodeValue,
            );
        array_push($feed, $item);
    }

    $limit = 5;

    for($x=0;$x<$limit;$x++) {
        $title = str_replace(' & ', ' &amp; ', $feed[$x]['title']);
        $link = $feed[$x]['link'];
        $description = $feed[$x]['desc'];
        $date = date('l F d, Y', strtotime($feed[$x]['date']));
        echo '<div><strong><a href="'.$link.'" title="'.$title.'">'.$title.'</a></strong><br />';


        echo $description.'</div>';

    }

The $description variable is an array value, which is a table. So i can't format the content of the table without putting it in an array.

<table border="0" cellpadding="8"><tbody><tr><td width="80px"><a href="http://www.ebay.co.uk/example"><img border="0" src="http://example.jpg"></a></td><td><div><span><strong>£145.00</strong></span></div><div>End Date: <span>13-Aug 16:14</span></div><div>Buy It Now for only: US £145.00</div><a href="http://www.ebay.co.uk/example">Buy it now</a><span>  |  </span><a href="http://cgi1.ebay.co.uk/example">Add to watch list</a></td></tr></tbody></table>

How do i get the content(including tags) of td and put into an array?

I tried this but the array values are blank.

$table = new DOMDocument(); 
$table->loadHTML($description);
    $new_table = array();
    foreach ($table->getElementsByTagName('tr') as $node) {
        $item = array ( 
            'cell' => $node->getElementsByTagName('td')->item(0)->nodeValue
            );
        array_push($new_table, $item);
    }
