What are the benefits of using XPath over traditional array functions when working with XML data in PHP?

When working with XML data in PHP, using XPath provides a more efficient and concise way to navigate through the XML structure compared to traditional array functions. XPath allows for targeted searches and extractions of specific elements or attributes within the XML document, making it easier to work with complex XML structures. Additionally, XPath simplifies the code and reduces the need for nested loops and conditional statements, resulting in cleaner and more maintainable code. 

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

// Use XPath to find all <book> elements with a <title> child element
$books = $xml->xpath('//book[title]');

// Iterate through the matched elements
foreach ($books as $book) {
    echo $book->title . "<br>";
}
