How can one effectively utilize the extendability of DOMDocument and DOMNode in PHP for creating and managing complex DOM structures?

To effectively utilize the extendability of DOMDocument and DOMNode in PHP for creating and managing complex DOM structures, you can create custom classes that extend these built-in classes to add additional functionality or encapsulate specific logic. By extending these classes, you can tailor the behavior of the DOM elements to suit your specific needs, making it easier to work with complex DOM structures. 

<?php

class CustomDOMDocument extends DOMDocument {
    // Add custom methods or properties here
}

class CustomDOMNode extends DOMNode {
    // Add custom methods or properties here
}

// Example of creating a custom DOMDocument object
$customDoc = new CustomDOMDocument();
$customDoc->loadXML('<root><element>Example</element></root>');

// Example of creating a custom DOMNode object
$customNode = $customDoc->getElementsByTagName('element')->item(0);
echo $customNode->nodeValue;

?>
