DOMDocument::importNode() example

Copying nodes between documents.

<?php
 
$orgdoc = new DOMDocument;
$orgdoc->loadXML("<root><element><child>text in child</child></element></root>");
 
// The node we want to import to a new document
$node = $orgdoc->getElementsByTagName("element")->item(0);
 
 
// Create a new document
$newdoc = new DOMDocument;
$newdoc->formatOutput = true;
 
// Add some markup
$newdoc->loadXML("<root><someelement>text in some element</someelement></root>");
 
echo "The 'new document' before copying nodes into it:\n";
echo $newdoc->saveXML();
 
// Import the node, and all its children, to the document
$node = $newdoc->importNode($node, true);
// And then append it to the "<root>" node
$newdoc->documentElement->appendChild($node);
 
echo "\nThe 'new document' after copying the nodes into it:\n";
echo $newdoc->saveXML();
?>

The above example will output:

The 'new document' before copying nodes into it:
<?xml version="1.0"?>
<root>
  <someelement>text in some element</someelement>
</root>

The 'new document' after copying the nodes into it:
<?xml version="1.0"?>
<root>
  <someelement>text in some element</someelement>
  <element>
    <child>text in child</child>
  </element>
</root>
