What are the advantages and disadvantages of using SimpleXML versus DOMDocument for handling XML documents with namespaces in PHP?

When handling XML documents with namespaces in PHP, SimpleXML is easier to use and has a simpler syntax compared to DOMDocument. However, SimpleXML does not handle namespaces as effectively as DOMDocument, which provides more flexibility and control over namespace handling. 

// Using DOMDocument to handle XML documents with namespaces in PHP
$xml = '<root xmlns:ns="http://example.com"><ns:element>Value</ns:element></root>';
$doc = new DOMDocument();
$doc->loadXML($xml);

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

$elements = $xpath->query('/ns:root/ns:element');
foreach ($elements as $element) {
    echo $element->nodeValue; // Output: Value
}
