Example #1 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 '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>
