What are common pitfalls when trying to extract specific parameters from an XML response in PHP?

One common pitfall when trying to extract specific parameters from an XML response in PHP is not properly navigating the XML structure. To avoid this, you should use XPath to target the specific elements you need. Another common issue is not handling namespaces correctly, which can lead to not being able to access the desired elements. Make sure to register and use namespaces when necessary. 

// Sample XML response
$xml = '<response>
            <data>
                <name>John Doe</name>
                <age>30</age>
            </data>
        </response>';

// Load the XML response
$response = simplexml_load_string($xml);

// Use XPath to extract specific parameters
$name = $response->xpath('//name')[0];
$age = $response->xpath('//age')[0];

echo "Name: " . $name . "\n";
echo "Age: " . $age;
