Output contents of an element with a specific class name

[Jonathan]

I want to input an html document manually and then have just the
content of certain element output back to me.

This is what my php looks like.

<?php
require('phpquery/phpQuery.php');
phpQuery::$debug = 1;

$html = $_POST['fullHTML'];

$doc = phpQuery::newDocument($html);

print $doc->find('ul.benefits');

?>

And what I get back is the following:

string(30) "Loading HTML, isXML() == false" string(275) "Full markup
load (HTML):
Array
(
[0] => FIND
[1] => ul.benefits
[2] => Array
(
[0] => Array
(
[0] =>
[1] => ul
[2] => .benefits
)

)

)
XPATH: //ul[@class]
QUERY FETCHED

Am I doing something wrong?
