我已經使用$ XML =新的SimpleXMLElement（ 'XML這裏數據'）然後使用 $ X = $ XML->的xpath（'/ ALEXA）; 我在這裏獲取如何訪問LINKSIN NUM和REACH排名。如果我發送$ x的foreach像 foreach（$ x as $ y）{ $ y-> LINKSIN NUM; } 它會拋出錯誤，因爲有LINKSIn和NUM如何解析這個XML數據使用PHP？

可能的重複[一個簡單的程序到CRUD節點和xml文件的節點值]（http://stackoverflow.com/questions/4906073/a-simple-program-to-crud-node-and-node-values -of-xml-file） – Gordon 2012-01-11 11:38:04

請看看xml的標記/縮進。 – 2012-01-11 12:06:43

之間的差距這應該工作：

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

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

如果您對XML的URL：

$xml = simplexml_load_file($URL_to_file);

'$ rank =（int）$ xml-> SD-> REACH ['rank'];' – YuS 2012-01-11 11:26:04

好的，縮進... – 2012-01-11 11:26:31

'$ rank =（int）$ xml-> SD-> REACH ['RANK 「];'。案件事宜。 – dfsq 2012-01-11 11:37:04

試試這個：

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

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

謝謝..有用！ – user1131409 2012-01-12 08:54:12
