What are best practices for navigating through nested XML elements in PHP?

When navigating through nested XML elements in PHP, it is best practice to use the SimpleXMLElement class provided by PHP. This class allows you to easily traverse through the XML structure using object-oriented syntax. You can access child elements by using the arrow operator (->) and iterate through them using loops or recursive functions. 

$xml = simplexml_load_string($xmlString);

foreach ($xml->children() as $child) {
    // Access attributes or values of current element
    echo $child->getName() . ": " . $child . "<br>";

    // Check if element has children
    if ($child->count() > 0) {
        // Recursive function to navigate through nested elements
        navigateXML($child);
    }
}

function navigateXML($element) {
    foreach ($element->children() as $child) {
        // Access attributes or values of current element
        echo $child->getName() . ": " . $child . "<br>";

        // Check if element has children
        if ($child->count() > 0) {
            // Recursive function to navigate through nested elements
            navigateXML($child);
        }
    }
}
