$dom = new DOMDocument();
$dom->load("library.xml");
$xpath = new DomXPath($dom);
$xpath->registerNamespace("lib", "http://example.org/library");
$result = $xpath->query("//lib:book");
$clone = $result->item(0)->cloneNode();
$result->item(1)->parentNode->appendChild($clone);
Modifying Data
When modifying data, you typically want to edit the CDATA within a node. Apart
from using the methods shown above, you can use XPath to find a CDATA node and
modify its contents directly:
$xml = item(0);
$node->data = ucwords($node->data);
echo $dom->saveXML();

In this example, we apply ucwords() to the text() node’s data property. The transformation
is applied to the original document, resulting in the following output:
Some Text Here
