Set NodeValues to Array Help

[twittoris]

I would like to place the output of these node values into an array:

foreach ($rows as $row) 
    { 
        /*** get each column by tag name ***/ 
	$cols = $row->getElementsByTagName('td');
        /*** echo the values ***/ 
        echo $cols->item(0)->nodeValue.'<br />'; 
        echo $cols->item(1)->nodeValue.'<br />'; 
        echo '<hr />'; 
    }

 

If the echo $cols->item(0)->nodeValue.'<br />'; always returns 6 values how can I call the values of each node later?
