如何在PHP中將XML子節點值保存到數據庫

Question

我需要關於將XML數據保存到MySQL數據庫的幫助。這裏是我的代碼：

<?xml version="1.0" encoding="UTF-8"?><Response Code="200"><Description>http://sample.net</Description><URL>/Patient/PatientView.aspx?pid=642</URL></Response> 

現在我想做的事是讓<Description>標籤和<URL>標籤的值並將它們組合成爲一個完整的URL，然後將它保存到MySQL數據庫。

看到這裏的問題How do you parse and process HTML/XML in PHP?

可以使用的SimpleXML（見http://php.net/manual/en/simplexml.examples-basic.php）解析

$xmlStr = '<?xml version="1.0" encoding="UTF-8"?><Response Code="200"><Description>http://sample.net</Description><URL>/Patient/PatientView.aspx?pid=642</URL></Response>'; 

$response = new SimpleXMLElement($xmlStr); 

$url = (string) $response->Description . (string) $response->URL; 

$url將包含：

http://sample.net/Patient/PatientView.aspx?pid=642 

然後使用PDO（http://php.net/manual/en/book.pdo.php）將數據存儲到數據庫：

try { 
    $dbh = new PDO('mysql:host=localhost;dbname=test', $user, $pass); 
    $stmt = $dbh->prepare("INSERT INTO sample (url) VALUES (:url)"); 
    $stmt->bindParam(':url', $url); 
    $stmt->execute(); 
} catch (PDOException $e) { 
    print "Error!: " . $e->getMessage() . "<br/>"; 
    die(); 
}
