How can one ensure that all nodes within a specific node are properly accessed and displayed using SimpleXML in PHP?

To ensure that all nodes within a specific node are properly accessed and displayed using SimpleXML in PHP, you can iterate through each child node of the parent node using a foreach loop. This way, you can access and display all the child nodes and their values.

$xml = simplexml_load_file('data.xml');

foreach ($xml->parent->children() as $child) {
    echo $child->getName() . ': ' . $child . '<br>';
}
