xml - xsd:sequence: 发现问题开始于：simpleType

Question

所以我在针对 XSD 验证 XML 时遇到了这个错误

Error - Line 38, 44: org.xml.sax.SAXParseException; lineNumber: 38; columnNumber: 44; s4s-elt-must-match.1: The content of 'sequence' must match (annotation?, (element | group | choice | sequence | any)*). A problem was found starting at: simpleType.
Error - Line 43, 41: org.xml.sax.SAXParseException; lineNumber: 43; columnNumber: 41; s4s-elt-must-match.1: The content of 'sequence' must match (annotation?, (element | group | choice | sequence | any)*). A problem was found starting at: simpleType.

简而言之

S4s-elt-must-match.1: The Content Of 'sequence' Must Match (annotation?, (element | Group | Choice | Sequence | Any)*). A Problem Was Found Starting At: SimpleType.

我附上我的 xml 和 xsd 文件以供参考，

我在网上看到很多帖子都出现了类似的错误错误。我检查了我的代码，我找不到问题。我想可能是因为 xs 而不是 xsd，但我不认为这是错误。我想我已经把 simpleType 和 complexType 放在了正确的位置。请告诉我。

我修复了 XSD。您只是错过了声明这两个元素：emailAddress和mobileNum。

尽管现在无法根据实际值验证输入 XML。

XSD 验证错误
