Simple DOM and <li>

I've tried this a few different ways and nothing seems to work. (I tried all examples at How to imitate child selector with Simple HTML DOM?) Used code as is, changing what I needed for my needs, ie class=xxx and the url.

So I'm trying pull out some information from a web page. There are no children to work with as far as DOM is concerned and using the xpath method got me nothing returned. I'm guessing I'm doing something wrong. 

<div id="wpp-6" class="widget popular-posts">
    <div class="widget_title">POPULAR</div><!-- Wordpress Popular Posts Plugin v2.3.2         [Widget] [daily] [regular] -->
    <ul>
        <li>
            <a href="http://link.html" title="Title of post" class="wpp-post-title">THE DATA I    WANT</a> <span class="post-stats"></span>
        </li>
        <!-- More lists -->
    </ul>
</div>

There are about 9 more list statements after that. Any suggestions?

Useing PHP Simple HTML DOM Parser you can do it easily, Just download the simple_html_dom.php file from here and use it as follows.

include('simple_html_dom.php');
$html=file_get_html('http://psfk.com');
foreach($html->find('div#wpp-6 ul li a') as $a){
    echo $a->innertext.'<br />';
}

It's been a while since I used xpath so here is my solution You can traverse DOM tree this way, checking for id and class of needed element

<?php
    error_reporting(0); //needed because of invalid xml




    $url = "http://www.psfk.com";

    $xml = new DOMDocument("1.0", 'UTF-8'); 
    $str = file_get_contents($url);


    // Load the url's contents into the DOM 
    $xml->loadHTML($str); 



    //Loop through all divs in the dom until we find what we need 
    foreach($xml->getElementsByTagName('div') as $div) {
        if($div->getAttribute('id') == 'wpp-6' && $div->getAttribute('class') == 'widget popular-posts') {
            if($div->parentNode->getAttribute('id') == 'right') {
                foreach($div->getElementsByTagName('li') as $li) {
                    foreach($li->getElementsByTagName('a') as $link) {
                        echo $link->textContent . "<br>";;
                    }
                }
            }
        }


    }

?>
