范例
Example #1 tidy::root() example
<?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); } }}?>
以上例程会输出：
..html ....head ......title ....body ......p ........"paragraph" ......br
