我更新了这个 post 代码更好，希望更容易理解。我仍然收到与上面相同的错误消息。
你的 XML 不是 well-formed because it has multiple root elements. An XML document may only have 。
修复此问题的选项：
- 删除第一个元素之后的所有
Team 个元素，或者
- 将所有
Team 元素包装在单个根元素中，例如 Teams.
选项 #1 就足够了；选项 #2 需要将 Teams 包装器元素添加到您的 XSD.
您的架构表示 Teams 元素包含一系列 Player 元素。但是在您的 XML 实例中， Teams 元素包含一系列 Team 元素。所以它期望找到一个 Player 元素，但它找到了一个 Team 元素，这就是为什么它抱怨说
Invalid content was found starting with element 'Team'. One of '{"":Player}' is expected.
请注意，符号 {"":Player} 表示没有命名空间的 Player 元素。它这样解释的原因是这个错误通常是由于使用了不正确的命名空间引起的（但不是你的情况）。
这是我第一次在这里提问，如果格式不正确请见谅。
谁能帮我理解这个错误：
cvc-complex-type.2.4.a: Invalid content was found starting with element 'Team'. One of '{"":Player}' is expected.

我更新了这个 post 代码更好，希望更容易理解。我仍然收到与上面相同的错误消息。
你的 XML 不是 well-formed because it has multiple root elements. An XML document may only have
修复此问题的选项：
- 删除第一个元素之后的所有
Team个元素，或者 - 将所有
Team元素包装在单个根元素中，例如Teams.
选项 #1 就足够了；选项 #2 需要将 Teams 包装器元素添加到您的 XSD.
您的架构表示 Teams 元素包含一系列 Player 元素。但是在您的 XML 实例中， Teams 元素包含一系列 Team 元素。所以它期望找到一个 Player 元素，但它找到了一个 Team 元素，这就是为什么它抱怨说
Invalid content was found starting with element 'Team'. One of '{"":Player}' is expected.
请注意，符号 {"":Player} 表示没有命名空间的 Player 元素。它这样解释的原因是这个错误通常是由于使用了不正确的命名空间引起的（但不是你的情况）。
