Are there best practices for handling namespace errors when working with XML documents in PHP?

When working with XML documents in PHP, namespace errors can occur when trying to access elements or attributes within a specific namespace. To handle these errors, it is recommended to use the `getElementsByTagNameNS` method to specify the namespace URI when querying for elements. This ensures that the correct elements are selected even if they are within a namespace. 

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

$xpath = new DOMXPath($xml);
$xpath->registerNamespace('ns', 'http://example.com/namespace');

$elements = $xpath->query('//ns:element', $xml->documentElement);

foreach ($elements as $element) {
    // Handle the element within the specified namespace
    echo $element->nodeValue;
}
