我使用了$ xml = new SimpleXMLElement（＆＃39; xml data here＆＃39;）然后使用 $ X = $ XML-＆GT;的xpath（＆＃39; / ALEXA）; 我在这里获得如何访问LINKSIN NUM和REACH RANK。如果我发送$ x in foreach就像 foreach（$ x as $ y）{ $ y-＆gt; LINKSIN NUM; } 它将抛出错误，因为LINKSIn和NUM

之间存在差距

Answer 1

这应该有效：

$xml = simplexml_load_string($dataHere);
$rank = (int)$xml->SD->REACH['RANK'];

文档：http://nl3.php.net/simplexml_load_string

如果您有xml的URL：

$xml = simplexml_load_file($URL_to_file);

Answer 2

试试这个：

$xml = simplexml_load_string($xml);
$links = $xml->xpath('//SD/LINKSIN');
$reach = $xml->xpath('//SD/REACH');

$num  = (int)$links[0]['NUM'];
$rank = (int)$reach[0]['RANK'];

如何使用PHP解析这个xml数据？
