简单XML问题

Question

也许有人可以帮助我解决有关 SimpleXML 对象的问题。

我正在与authorize.net CIM 管理器集成并发送客户资料。当我发送它时，原始 xml 响应将通过解析器传递并转换为 SimpleXML 对象。

以下是用于提交请求的代码：

$content =
        "<?xml version=\"1.0\" encoding=\"utf-8\"?>".
        "<createCustomerProfileRequest xmlns=\"AnetApi/xml/v1/schema/AnetApiSchema.xsd\">".
        MerchantAuthenticationBlock().
        "<profile>".
        //"<merchantCustomerId>".$userInsertedId."</merchantCustomerId>". // Your own identifier for the customer.
        "<description>'New User Purchase'</description>".
        "<email>" . $_GET["email"] . "</email>".
        "<paymentProfiles>".
        "<billTo>".
         "<firstName>".$_GET["firstname"]."</firstName>".
         "<lastName>".$_GET["lastname"]."</lastName>".
         "<address>".$_GET["street"]."</address>".
         "<city>".$_GET["city"]."</city>".
         "<state>".$_GET["state"]."</state>".
         "<zip>".$_GET["zip"]."</zip>".
         "<country>".$_GET["country"]."</country>".
         "<phoneNumber>".$_GET["phone"]."</phoneNumber>".
        "</billTo>".
        "<payment>".
         "<creditCard>".
          "<cardNumber>".$_GET["number"]."</cardNumber>".
          "<expirationDate>".$_GET["year"]."-".$_GET["month"]."</expirationDate>". // required format for API is YYYY-MM
          "<cardCode>".$_GET["code"]."</cardCode>".
         "</creditCard>".
         "</payment>".
        "</paymentProfiles>".
        "</profile>".
        "<validationMode>testMode</validationMode>". 
        "</createCustomerProfileRequest>";

        $CCresponse = send_xml_request($content);

        //echo($CCresponse);

        $parsedresponse = parse_api_response($CCresponse);

   function parse_api_response($content)
        {
            $parsedresponse = simplexml_load_string($content, "SimpleXMLElement", LIBXML_NOWARNING);
            if ("Ok" != $parsedresponse->messages->resultCode) 
            {
                echo "The operation failed with the following errors:<br>";
                foreach ($parsedresponse->messages->message as $msg) 
                {
                    echo "[" . htmlspecialchars($msg->code) . "] " . htmlspecialchars($msg->text) . "<br>";
                }
                    echo "<br>";
            }
            return $parsedresponse;
        }

当我执行以下操作时：

$parsedresponse = parse_api_response($CCresponse);
print_r($parsedresponse);

我得到以下输出：

SimpleXMLElement Object
(
[messages] => SimpleXMLElement Object
    (
        [resultCode] => Ok
        [message] => SimpleXMLElement Object
            (
                [code] => I00001
                [text] => Successful.
            )
    )
[customerProfileId] => 15642446
[customerPaymentProfileIdList] => SimpleXMLElement Object
    (
        [numericString] => 13865552
    )
[customerShippingAddressIdList] => SimpleXMLElement Object
    (
    )
[validationDirectResponseList] => SimpleXMLElement Object
    (
        [string] => 1|1|1|(TESTMODE) This transaction has been approved.|000000|P|0|none|Test transaction for ValidateCustomerPaymentProfile.|1.00|CC|auth_only||*****|******||****|*******|******|******|USA|1234567890||[email protected]|none|none|none|none|none|none|none|none|0.00|0.00|0.00|FALSE|none|207BCBBF78E85CF174C87AE286B472D2

所以从这里看来一切都正常。但是，当我尝试深入研究 SimpleXML 对象并执行以下操作时：

echo $code = (string) $parsedresponse->messages->resultCode;

我得到“OkOk”的输出，看起来它运行了两次。这让我快疯了，我不明白这里到底发生了什么。有人可以在这里为我指明正确的方向，以便我可以正常工作吗？

谢谢！

也许您可以尝试使用 xpath 方法来导航 SimpleXMLElement，如下所示：

$code = (string) $parsedresponse->xpath('messages/resultCode');
echo $code;
