tidy_get_root

(PHP 5)

tidy_get_root --  Returns a tidyNode object representing the root of the tidy parse tree

Description

Procedural style:

tidyNode tidy_get_root ( tidy object )

Object oriented style:

tidyNode tidy->root ( void )

Returns a tidyNode object representing the root of the tidy parse tree.

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);
       }
   }
}
?>

上例将输出:

..html
....head
......title
....body
......p
........"paragraph"
......br

注: 本函数仅能用于 Zend Engine 2,这意味着 PHP >= 5.0.0。
