DOMNode.appendChild 如何添加另一个DOM里的节点？

This topic created in 4623 days ago, the information mentioned may be changed or developed.

$dom = new DOMDocument();
$dom->loadHTML("<html><body><div>111</div></body></html>");

$dom2 = new DOMDocument();
$dom2->loadHTML("<html><body></body></html>");

$body = $dom2->getElementsByName("body")->item(0);

$body->appendChild($dom->getElementsByName("div")->item(0));

这样会提示
Fatal error: Uncaught exception 'DOMException' with message 'Wrong Document Error' in test.php:10
Stack trace:
#0 test.php(10): DOMNode->appendChild(Object(DOMElement))
#1 {main}
thrown in test.php on line 10

我是获取到一个页面后，只想保留其中一个table里的特定信息，所以想说用一个新的document里装，但是一直提示这错误

body

HTML

test
