Scrape onclick url

Question

I want to scrape html with php and retrieve the js onclick url from specific table cells, the cells are always in identical pairs so I only need one url of every pair, for example:

<tr>
<td width='10' class='score' OnClick="window.location='page.99.html'">
<td width='10' class='score' OnClick="window.location='page.99.html'">
</tr>

I want to retrieve page.99.html from either these and carry on for however many pairs there are. I've been using this and can get the cell value but not the onclick propery:

$dom = new DOMDocument();
$res=$dom->loadHTML($html);
$xpath = new DomXPath($dom);
$cells = $xpath->query( '//td[@width="10"]');

foreach($cells as $cell) {
echo $cell->nodeValue;
}

Can anyone please tell me how to access this onclick url for each appropriate cell?

Have you tried var_dump($cell) to see what it contains?

Using simple dom:

$doc = str_get_html($str);
echo $doc->find('td[onclick]', 0)->onclick;

This should do it :

$onClicks = array();

$dom->loadHTML($html);

foreach($dom->getElementsByTagName('td') as $td) { 
    if((int)$td->getAttribute('width') == 10) {
        $onClicks[] = $td->getAttribute('OnClick'); 
    }
} 

foreach($onClicks as $onClick) {
    // do something...
    echo $onClick;
}

sorry, this is probably really stupid - $onClicks is an array storing the various onclick attributes right? How do access or print each element of the array? I can see it's 16 items long as it should be but not echo or fwrite them.
