例子 1. dump nodes

<?php

$html = <<< HTML
<html><body>

<p>paragraph</p>
<br/>

</body></html>
HTML;

$tidy = tidy_parse_string($html);
dump_nodes($tidy->root(), 1);


function dump_nodes($node, $indent) {

    if($node->hasChildren()) {
        foreach($node->child as $child) {
            echo str_repeat('.', $indent*2) . ($child->name ? $child->name : '"'.$child->value.'"'). "\n";

            dump_nodes($child, $indent+1);
