你好，我正在为一个使用WooCommerce的客户创建一个wordpress网站。该网站已经完成，但客户希望能够从shop_order页面创建发货。我已经解决了大部分问题，问题是我对UPS API的XML请求。我检查了又检查，似乎找不到错误：
<ShipmentConfirmResponse><Response><ResponseStatusCode>0</ResponseStatusCode><ResponseStatusDescription>Failure</ResponseStatusDescription><Error><ErrorSeverity>Hard</ErrorSeverity><ErrorCode>10002</ErrorCode><ErrorDescription>The XML document is well formed but the document is not valid</ErrorDescription></Error></Response></ShipmentConfirmResponse>
下面是我的xml标记，其中隐藏了敏感信息。

我几乎做到了，但我被困在了这个路障上。如果有人能对此有所了解，我们将不胜感激。
它是服务代码容器，必须包含在包容器中。我以前就犯过这个错误。我花了很长时间才弄清楚自己犯了这个愚蠢的错误。
之前：
...
<Service>
<Code>03</Code>

之后：

感谢您的帮助，是的，UPS需要一个奇怪的XML格式。
XML处理指令出现两次：
<?xml version="1.0" ?>
这表示存在两个不同的XML文档：
<?xml version="1.0" ?>
<AccessRequest xml:lang='en-US'>
<AccessLicenseNumber>******</AccessLicenseNumber>
<UserId>********</UserId>
<Password>********</Password>
</AccessRequest>
和
<?xml version="1.0" ?>
<ShipConfirmRequest xml:lang='en-US'>
<Request>
<TransactionReference>
<CustomerContext>Customer Context</CustomerContext>
<XpciVersion>1.0</XpciVersion>
</TransactionReference>
<RequestAction>ShipConfirm</RequestAction>
<RequestOption>validate</RequestOption>
</Request>
<!-- ... -->
</ShipConfirmRequest>
