PHP DOM删除标记（不是内容）

Question

$mystring="This is mystring. <a href='http://www.google.com'>Google.</a>"; 
$dom = new DOMDocument; 
$dom->loadHTML($mystring); 
$xPath = new DOMXPath($dom); 
$nodes = $xPath->query('//a');
if($nodes->item(0)) { 
    $nodes->item(0)->parentNode->removeChild($nodes->item(0)); 
} 
echo $dom->saveHTML();  

I want to get output:

This is mystring. Google.

But i got just:

This is mystring.

Try the following:

if($nodes->item(0)) {
    $node = $nodes->item(0);
    $node->parentNode->replaceChild(new DOMText($node->textContent), $node); 
}
