How can namespaces be effectively bound in SimpleXML to avoid errors when accessing elements?

When working with XML data that contains namespaces in SimpleXML, it's important to bind the namespaces to avoid errors when accessing elements. This can be done by using the `registerXPathNamespace` method to define a prefix for each namespace used in the XML document. By binding the namespaces correctly, you can access elements without encountering errors related to namespace ambiguity. 

$xml = simplexml_load_string($xmlString);

// Define namespaces
$xml->registerXPathNamespace('ns1', 'http://example.com/ns1');
$xml->registerXPathNamespace('ns2', 'http://example.com/ns2');

// Access elements using the defined prefixes
$elements = $xml->xpath('//ns1:element/ns2:subelement');

foreach ($elements as $element) {
    // Process elements
}
