How to create a DOMNode in PHP?

The class DOMNode doesn't provide a contructor and also no static methods like createInstance(). So, how to create an DOMNode instance?

Solution

  • Create a DOMDocument. It extends from DOMNode, has a constructor, and represents the rootnode of a document. Being a DOMNode, DOMDocument has methods for adding children. For instance, DOMDocument has a method CreateElement, which returns a DOMElement, which also inherits from DOMNode.
    All in all, it seems that DOMNode is just the base class and shouldn't be used directly.

    <?php

$dom = new DOMDocument('1.0', 'utf-8');

$element = $dom->createElement('test', 'This is the root element!');

// We insert the new element as root (child of the document)
$dom->appendChild($element);

echo $dom->saveXML();
?>

    (Example taken from the CreateElement documentation)
