Are there any alternative methods or libraries in PHP that offer more efficient ways to delete nodes from an XML document compared to SimpleXML's unlink function?

SimpleXML's unlink function can be inefficient when deleting nodes from large XML documents because it requires the entire document to be loaded into memory. One alternative method is to use the DOM extension in PHP, which allows for more efficient manipulation of XML documents, including deleting nodes. By using the DOM extension, you can selectively delete nodes without having to load the entire document into memory. 

// Load the XML document using DOM
$xml = new DOMDocument();
$xml->load('example.xml');

// Find the node(s) to delete
$nodesToDelete = $xml->getElementsByTagName('node');

// Loop through and delete each node
foreach ($nodesToDelete as $node) {
    $node->parentNode->removeChild($node);
}

// Save the modified XML document
$xml->save('example.xml');
