PHP | DOMDocument importNode() Function

The DOMDocument::importNode() function is an inbuilt function in PHP which is used to return a copy of the node which need to import and associates it with the current document. Syntax:

DOMNode DOMDocument::importNode( DOMNode $importedNode, bool $deep = FALSE )

Parameters: This function accepts two parameters as mentioned above and described below:

$importedNode: This parameter holds the node which need to import.
$deep: This parameter holds the Boolean value. If it set to TRUE then it will recursively import the subtree under the importedNode.

Return Value: This function returns the copied node on success or FALSE, if it cannot be copied. Below program illustrates the DOMDocument::importNode() function in PHP: Program:

php

<?php

// Create a new document
$dom = new DOMDocument;

// Load the XML document
$dom->loadXML("<root><contact><email>abc@geeksforgeeks.org</email>
<mobile>+91-987654321</mobile></contact></root>");

// Use getElementsByTagName() function to search
// all elements with given local tag name
$node = $dom->getElementsByTagName("contact")->item(0);

// Create a new document
$dom1 = new DOMDocument;

$dom1->formatOutput = true;

// Load the XML document
$dom1->loadXML("<root><contactinfo><email>abc@geeksforgeeks.org</email>
<mobile>+91-987654321</mobile></contactinfo></root>");

echo "Document before copying the nodes\n";

// Save the file in XML and display it
echo $dom1->saveXML();

// Use importNode() function to import the node
$node = $dom1->importNode($node, true);

// Append child to the document
$dom1->documentElement->appendChild($node);

echo "\nDocument after copying the nodes\n";

// Save XML document and display it
echo $dom1->saveXML();

?>

Output:

Document before copying the nodes
<?xml version="1.0"?>
<root>
    <contactinfo><email>abc@geeksforgeeks.org</email>
    <mobile>+91-987654321</mobile></contactinfo>
</root>
Document after copying the nodes
<?xml version="1.0"?>
<root>
    <contactinfo><email>abc@geeksforgeeks.org</email>
