What are some common methods for deleting elements in a PHP XML file using simpleXML?

When working with PHP and simpleXML to manipulate XML files, you may encounter the need to delete elements from the XML structure. One common method to achieve this is by using unset() function to remove the desired element from the XML document. This function allows you to unset a specific element or attribute within the XML structure. 

// Load the XML file
$xml = simplexml_load_file('data.xml');

// Find the element to delete (e.g. <element>)
$elementToDelete = $xml->xpath('//element');

// Unset the element
unset($elementToDelete[0]);

// Save the changes back to the XML file
$xml->asXML('data.xml');
