What potential issues could arise when trying to access specific elements in a complex XML structure using PHP?

One potential issue that could arise when trying to access specific elements in a complex XML structure using PHP is navigating through nested elements or attributes. To solve this, you can use XPath to specify the exact path to the element you want to access within the XML document. 

$xml = simplexml_load_file('complex.xml');
$element = $xml->xpath('/root/parent/child/subchild');
if ($element) {
    // Access the specific element
    echo $element[0];
} else {
    echo "Element not found";
}
