Are there any best practices for validating XML files in PHP using the DOMDocument class?

When working with XML files in PHP, it is important to validate the XML structure to ensure its correctness. One way to validate XML files in PHP is by using the DOMDocument class, which provides methods for loading, parsing, and validating XML documents against a specified schema. Here is a simple PHP code snippet that demonstrates how to validate an XML file using the DOMDocument class: 

$dom = new DOMDocument();
$dom->load('example.xml');

if ($dom->validate()) {
    echo 'XML is valid.';
} else {
    echo 'XML is not valid.';
}
