xml - 错误 : The content of 'persons' must match (annotation? , (simpleType | complexType)?, (unique | key | keyref)*))

Question

我正在尝试为 XML 键入 XSD，但发生错误。我不知道为什么会这样。我是 XML 的新手，所以不太了解它。 错误是:

Exception: s4s-elt-must-match.1: The content of 'persons' must match (annotation?, (simpleType | complexType)?, (unique | key | keyref)*)). A problem was found starting at: complexType.

非常感谢任何帮助或建议。

我正在尝试编写的 XSD

Answer 1

需要两个修复:

1. 在复杂类型之前关闭 person 的 xs:element 标签 其余类型的声明。
2. 修正一个拼写错误:stubject 应该是 `subjection.

总而言之，以下 XSD 将成功验证您的 XML 文档:

      </xs:sequence>
    </xs:complexType>
  </xs:element>
  <xs:complexType name="personType">
    <xs:sequence>
      <xs:element name="name" type="xs:string"/>

      <xs:element name="gender" type="xs:string"/>
      <xs:element name="address" type="addType"/>
      <xs:element name="student" maxOccurs="unbounded" minOccurs="0" type="studentType"/>
