tidyNode::getParent — Returns the parent node of the current node
此函数没有参数。
Returns a tidyNode if the node has a parent, or null
otherwise.
Example #1 tidyNode::hasChildren() example
<?php
$html = <<< HTML
<html><head>
<?php echo '<title>title</title>'; ?>
<#
/* JSTE code */
alert('Hello World');
#>
</head>
<body>
Hello World
</body>
</html>
HTML;
$tidy = tidy_parse_string($html);
$num = 0;
$node = $tidy->html()->child[0]->child[0];
var_dump($node->getparent()->name);
?>
以上例程会输出：
string(4) "head"
