How can PHP developers avoid only retrieving the first element and value from an XML file?

When retrieving data from an XML file in PHP, developers often encounter issues where they only retrieve the first element and value. To avoid this, developers can use PHP's DOMDocument class to parse the entire XML file and access all elements and values. By using methods like getElementsByTagName(), developers can loop through all elements and retrieve their values. 

<?php
$xml = file_get_contents('example.xml');
$dom = new DOMDocument();
$dom->loadXML($xml);

$elements = $dom->getElementsByTagName('*');
foreach ($elements as $element) {
    echo $element->tagName . ': ' . $element->nodeValue . '<br>';
}
?>
