Exemple de code PHP utilisant XPath pour analyser le HTML

$xml = simplexml_load_file('https://forums.eveonline.com'); 

$names = $xml->xpath("html/body/p/p/form/p/p/p/p/p[*]/p/p/table//tr/td[@class='topicViews']"); 
foreach($names as $name) 
{ 
    echo $name . "<br/>"; 
}

$url = 'http://www.baidu.com';
$ch = curl_init();
curl_setopt($ch, CURLOPT_FILE, fopen('php://stdout', 'w'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_URL, $url);
$html = curl_exec($ch); 
curl_close($ch);

// create document object model
$dom = new DOMDocument();
// load html into document object model
@$dom->loadHTML($html);
// create domxpath instance
$xPath = new DOMXPath($dom);
// get all elements with a particular id and then loop through and print the href attribute
$elements = $xPath->query('//*[@id="lg"]/img/@src');
foreach ($elements as $e) {
  echo ($e->nodeValue);
