<ul><li>1</li><li>2</li><li>3</li><li><a href="http:abc.com">4</a></li></ul>

I have tried with the following code but i am not able to find the last li…
require_once 'simple_html_dom.php';
$html = "<ul><li>1</li><li>2</li><li>3</li><li><a href="http:abc.com">4</a></li></ul>";
$oDocumentModel = new simple_html_dom();
$oDocumentModel->load($html);
$ul = $oDocumentModel->find('ul',0);

You can loop through the li and convert it in array and find the last element. if you have smaller set of li like…
require_once 'simple_html_dom.php';
$html = "<ul><li>1</li><li>2</li><li>3</li><li><a href='http:abc.com'>4</a></li></ul>";
$oDocumentModel = new simple_html_dom();
$oDocumentModel->load($html);
$ul = $oDocumentModel->find('ul',0);
$items = array();
foreach( $ul->find('li') as $li ){
$items[] = $li->plaintext;
}
$last = end($items);
print_r($last);
Or you can use lastChild() just go through the http://simplehtmldom.sourceforge.net/manual_api.htm

You can extract the link this way.
$ul = $oDocumentModel->find('ul',0);
$a = $ul -> lastChild() -> find('a'. 0);
$href = $a -> href;
