当我验证我的 xml 文件时，我得到以下异常
When I validate my xml file i get the following Exception
org.xml.sax.SAXParseException; systemId: file:/C://xml//c2.xsd; lineNumber: 22;
columnNumber: 37; s4s-elt-invalid-content.1: The content of '#AnonType_Reference
SignedInfoSignature' is invalid. Element 'element' is invalid, misplaced, or oc
curs too often.
我不知道我哪里出错了?谁能告诉我代码中的错误到底在哪里?
编辑 1 后出错
org.xml.sax.SAXParseException; systemId: file:/C://xml//c2.xsd; lineNumber: 22;
columnNumber: 15; s4s-elt-invalid-content.1: The content of '#AnonType_Reference
SignedInfoSignature' is invalid. Element 'all' is invalid, misplaced, or occurs
too often.
推荐答案
在c2.xsd，第22行
At c2.xsd, line 22
<xs:complexType>
<xs:attribute name="URI" type="xs:string"/>
<xs:element name="Transforms">
xs:element 不能作为 xs:complexType 的直接子级出现.它必须在 xs:all、xs:choice 或 xs:sequence 内.
xs:element cannot appear as a direct child of xs:complexType. It must be inside xs:all, xs:choice or xs:sequence.
