本文分享关于php用xpath解析html的代码实例讲解
实例1
$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/>";
}
实例2
$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);
}
