What potential issues or errors can arise when trying to access specific data elements in a complex XML array structure in PHP?

When trying to access specific data elements in a complex XML array structure in PHP, potential issues can arise due to the nested nature of the XML elements. One common error is not properly navigating through the array structure to reach the desired data element. To solve this, you can use PHP's SimpleXMLElement class along with XPath queries to easily access specific data elements within the XML array. 

// Load the XML file into a SimpleXMLElement object
$xml = simplexml_load_file('data.xml');

// Use XPath to access specific data elements within the XML array
$elements = $xml->xpath('//parent/child/grandchild');

// Loop through the elements and output their values
foreach ($elements as $element) {
    echo $element . "<br>";
}
