How can PHP developers efficiently search for specific data within multiple elements in XML?

To efficiently search for specific data within multiple elements in XML, PHP developers can use XPath queries. XPath is a powerful query language for selecting nodes in an XML document. By using XPath, developers can easily navigate through the XML structure and locate the desired data. 

$xml = simplexml_load_file('data.xml');

// Search for all <book> elements with <title> containing 'PHP'
$books = $xml->xpath("//book[contains(title, 'PHP')]");

foreach ($books as $book) {
    echo $book->title . "\n";
}
