Introduction

SimpleXML is a PHP extension that provides a simple and easy-to-use API for working with XML documents. The SimpleXMLElement::importNode() function is one of the many functions that SimpleXML provides to work with XML documents. It is a powerful tool that can be used to import a DOM node into a SimpleXMLElement object. In this article, we will be discussing the SimpleXMLElement::importNode() function in detail and how it can be used in PHP.

Understanding the SimpleXMLElement::importNode() function

The SimpleXMLElement::importNode() function in PHP imports a DOM node into a SimpleXMLElement object. The syntax for using the SimpleXMLElement::importNode() function is as follows:

importNode ( DOMNode $node ) : SimpleXMLElement

Here, $node is the DOM node to import.

Example Usage

Let's look at an example to understand the usage of the SimpleXMLElement::importNode() function in PHP:

<?php

$dom = new DOMDocument();
$element = $dom->createElement('title', 'PHP Basics');
$dom->appendChild($element);
$xml = new SimpleXMLElement('<book></book>');
$xmlDom = dom_import_simplexml($xml);
$xmlElement = $xmlDom->ownerDocument->importNode($element, true);
$xmlDom->appendChild($xmlElement);
echo $xml->asXML();

In the example above, we first create a DOMDocument object and use it to create a DOM element containing the title "PHP Basics". We then create a SimpleXMLElement object that represents an XML document containing a book element. We use the importNode() method to import the DOM element into the SimpleXMLElement object, and finally, we print the string representation of the XML document.
