How can PHP developers effectively handle errors related to non-existent attributes or elements in XML parsing?

When parsing XML in PHP, developers can effectively handle errors related to non-existent attributes or elements by using error handling techniques such as try-catch blocks or checking for the existence of attributes or elements before accessing them. This can help prevent runtime errors and improve the overall robustness of the code. 

try {
    $xml = simplexml_load_string($xmlString);

    if(isset($xml->element->attribute)) {
        // Access the attribute
        $attributeValue = $xml->element->attribute;
    } else {
        // Handle the case when the attribute does not exist
        // For example, set a default value or log a warning
    }
} catch (Exception $e) {
    // Handle any parsing errors
    echo 'Error parsing XML: ' . $e->getMessage();
}
