In what scenarios would it be beneficial to use XPath to extract data from XML in PHP instead of traditional array methods?

Using XPath to extract data from XML in PHP can be beneficial in scenarios where the XML structure is complex and nested, making it difficult to traverse using traditional array methods. XPath allows for more precise querying of specific elements or attributes within the XML document, saving time and effort compared to manually iterating through arrays. Additionally, XPath provides a standardized way to access XML data, making the code more readable and maintainable. 

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

// Use XPath to extract data
$nodes = $xml->xpath('//book[@category="fiction"]/title');

// Output the results
foreach ($nodes as $node) {
    echo $node . "<br>";
}
