<?php echo '<title>title</title>'; ?>
<# 
  /* JSTE code */
  alert('Hello World'); 
#>
</head>
<body>

<?php
  // PHP code
  echo 'hello world!';
?>

<%
  /* ASP code */
  response.write("Hello World!")
%>

<!-- Comments -->
Hello World
</body></html>
Outside HTML
HTML;


$tidy tidy_parse_string($html);
$num 0;

get_nodes($tidy->html(), 'text');

function 
get_nodes($node$node_type) {

    
// check if the current node is of requested type
    
if($node->{"is$node_type"}()) {
        echo 
"\n\n# $node_type node #" . ++$GLOBALS['num'] . "\n";
        echo 
$node->value;
    }

    
// check if the current node has childrens
    
if($node->hasChildren()) {
        foreach(
$node->child as $child) {
            
get_nodes($child$node_type);
        }
    }
}

?>

The above example will output:

# jste node #1
<# 
  /* JSTE code */
  alert('Hello World'); 
#>

/*
var_dump($tidy->html()->child[0]->hasChildren());
var_dump($tidy->html()->child[0]->child[0]->hasChildren());
*/
