How can namespaces in SimpleXML affect the extraction of specific data elements from XML files?

Namespaces in SimpleXML can complicate the extraction of specific data elements from XML files because they require special handling to access nodes with namespace prefixes. One way to solve this issue is by using the `->children()` method along with the namespace URI to access nodes with namespaces. 

$xml = '<root xmlns:ns="http://example.com"><ns:element>Value</ns:element></root>';
$simplexml = simplexml_load_string($xml);

$namespaces = $simplexml->getNamespaces(true);
$ns = $simplexml->children($namespaces['ns']);

$value = (string) $ns->element;

echo $value; // Output: Value
