如何在PHP中将XML子节点值保存到数据库

Question

我需要关于将XML数据保存到MySQL数据库的帮助。这里是我的代码：

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

现在我想做的事是让<Description>标签和<URL>标签的值并将它们组合成为一个完整的URL，然后将它保存到MySQL数据库。

看到这里的问题How do you parse and process HTML/XML in PHP?

可以使用的SimpleXML（见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将包含：

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

然后使用PDO（http://php.net/manual/en/book.pdo.php）将数据存储到数据库：

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(); 
}
