What is the purpose of using DOMDocument to parse XML or HTML files in PHP?

When parsing XML or HTML files in PHP, using DOMDocument allows for easy traversal and manipulation of the document's structure. This class provides methods for loading the file, navigating through its elements, and extracting data efficiently. By utilizing DOMDocument, developers can easily access specific elements, attributes, or text content within the XML or HTML file. 

// Create a new DOMDocument instance
$doc = new DOMDocument();

// Load the XML file
$doc->load('file.xml');

// Get elements by tag name
$elements = $doc->getElementsByTagName('element');

// Loop through the elements and extract data
foreach ($elements as $element) {
    echo $element->nodeValue . "\n";
}
