How can DOMXpath be used to search for specific HTML elements in PHP?

DOMXpath can be used in PHP to search for specific HTML elements by loading the HTML content into a DOMDocument object and then creating an XPath query to target the desired elements. This allows for more precise and flexible searching compared to using traditional DOM methods. The XPath query can be customized to target elements based on their tag name, attributes, or position within the document. 

$html = '<html><body><div class="content">Hello, World!</div></body></html>';

$dom = new DOMDocument();
$dom->loadHTML($html);

$xpath = new DOMXpath($dom);

// Search for all div elements with class "content"
$elements = $xpath->query("//div[@class='content']");

foreach ($elements as $element) {
    echo $element->nodeValue; // Output: Hello, World!
}
