 <li id="idli1" class="cls">List 1</li><li>List 2</li><li class="cls">List 3</li>
 </ul></nav>');

// Get the id of the first LI in UL, and change its content
$idli = $html->find('li', 0)->id;
if($idli) echo 'First LI id: '. $idli;
$html->find('ul li', 0)->innertext = '<b>PHP Simple HTML DOM</b>';
echo $html;

<?php
include('simplehtmldom/simple_html_dom.php');

// Create a DOM object from a HTML file
$html = file_get_html('test.htm');

// Write a function with parameter "$elm"
function changeCls($elm) {
  // if LI with class="cls", change the class
  if ($elm->tag=='li' && $elm->class=='cls') {
    $elm->setAttribute('class', 'class_2');
  }
} 
$html->set_callback('changeCls');
echo $html;
?>
