What are the potential pitfalls of using PHP namespaces in XML parsing?

When parsing XML with PHP namespaces, a potential pitfall is that you need to properly handle namespace prefixes in order to access the desired elements and attributes. One way to solve this is by using the `getNamespaces` method to retrieve all namespaces in the XML document and then prefixing the element or attribute names with the appropriate namespace. 

$xml = '<root xmlns:ns="http://example.com"><ns:element>Value</ns:element></root>';
$doc = new SimpleXMLElement($xml);
$namespaces = $doc->getNamespaces(true);

$ns = $doc->children($namespaces['ns']);
$value = (string)$ns->element;
echo $value; // Output: Value
