上下文：我正在尝试向 UPS 的 ShipAccept api 发送测试请求。我收到一条错误消息，告诉我 xml 文档格式不正确。我发送的实际请求包含所有必需的信息，这只是相同的格式。

<AccessRequest xml:lang="en-US">

另外，缩进对xml很重要吗？我的缩进错误的事实可能是文档格式不正确的原因吗？我对 xml 没有任何经验，但不幸的是，UPS api 接受大多数东西作为 json 除了运输部件。非常感谢您提前为我提供的任何帮助！

编辑：提供的代码是他们自己的正确请求示例，所以我很困惑。

一个 XML 文档只能有一个根。您在这里看到的是两个XML 文档，它们在第二个文档的声明中与一个错字连接在一起。

</AccessRequest>          <-- end of the root element of the 1st doc


</?xml version="1.0"?>   <-- Probably an XML declaration of the 2nd doc.
                             Shouldn't have the slash.
