What is the issue with accessing values from an XML string using simplexml in PHP?

When accessing values from an XML string using simplexml in PHP, you may encounter issues if the XML contains namespaces. To access values within namespaces, you need to register the namespaces and use them when querying the XML elements. 

// Load the XML string
$xmlString = '<root xmlns:ns="http://example.com"><ns:element>Value</ns:element></root>';
$xml = simplexml_load_string($xmlString);

// Register the namespace
$xml->registerXPathNamespace('ns', 'http://example.com');

// Access the value within the namespace
$value = $xml->xpath('//ns:element')[0];

echo $value; // Output: Value
