xsd：sequence：发现问题始于：simpleType

问题描述

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xml和xsd文件以供参考，

academics.xml

我在许多帖子中在线看到了类似的错误错误。我检查了我的代码，找不到问题。我认为可能是因为xs而不是xsd，但我不认为这是错误。我想我已经正确地设置了simpleType和complexType。请让我知道。

解决方法

我修复了XSD。您只是错过了声明两个元素： emailAddress 和 mobileNum 。

尽管现在无法根据实际值验证输入XML。

XSD

        </xs:restriction>
    </xs:simpleType>
    <xs:simpleType name="mobileNumType">
        <xs:restriction base="xs:string">
            <xs:pattern value="([0-9]{3}) [0-9]{3}-[0-9]{4}"/>
        </xs:restriction>
    </xs:simpleType>
</xs:schema>

XSD验证错误

Error The 'admissionYear' element is invalid - The value '2019/' is invalid according to its datatype 'http://www.w3.org/2001/XMLSchema:integer' - The string '2019/' is not a valid Integer value.
Error The 'mobileNum' element is invalid - The value '1234567890' is invalid according to its datatype 'mobileNumType' - The Pattern constraint failed.

错误是指xs:simpleType和emailAddress的{{1}}声明实际上应该是元素声明。（mobileNum不能作为xs:simpleType的子代出现，但是xs:sequence可以。）您可以在命名元素声明下匿名保留xs:element，就像其他XSD已经一样在该点之上使用xs:simpleType。

在对XSD进行了这些修复之后，您还会发现XML在以下两个方面不符合XSD：xs:complexType有一个流浪admissionYear字符，和/遵循错误的格式。请注意，如果您希望mobileNum是有效的(123) 456-7890，则还必须更新XSD，以在mobileNum正则表达式中转义(和)

以上所有修补程序已应用于以下XML和XSD，现已成功验证：
