What are some common pitfalls when accessing specific elements in XML structures using PHP?

One common pitfall when accessing specific elements in XML structures using PHP is not properly handling namespaces. When working with XML that uses namespaces, you need to account for them when querying elements. You can use the `->children()` method to access elements within a specific namespace. 

// Load the XML file
$xml = simplexml_load_file('file.xml');

// Define the namespace
$ns = $xml->getNamespaces(true)['ns'];

// Access elements within the namespace
$elements = $xml->children($ns)->element;
