当我验证我的 xml 文件时，我得到以下异常

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.

我无法弄清楚我哪里出错了？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.

Answer 1

在 c2.xsd，第 22 行

         <xs:complexType>
           <xs:attribute name="URI" type="xs:string"/>
           <xs:element name="Transforms">

xs:element不能作为 的直子出现xs:complexType。它必须在里面xs:all，xs:choice或xs:sequence。

Answer 2

我尝试了您的文件并设法让它针对notepad ++进行验证，并做了几件事：

1. 将 xsd 更改为使用对导入签名 xsd 的引用，而无需任何 c:\reference。为此，我只是将导入的文件复制到与我正在从中导入的 xsd 相同的位置
2. 将您指定 ds 的 c2.xsd 更改为不同的属性，即 dsig
3. 从w3 Signature xsd下载 w3c 版本的签名xsd并在导入中使用它（步骤 1）。
4. 在指定签名时更改了输出 xml 以包含 xmlns="http://www.w3.org/2000/09/xmldsig#" 行。

请注意我在下面的 notepad++ 中成功验证的 xsd 和 xml。

XSD：

<?xml version="1.0" encoding="utf-8" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:dsig="http://www.w3.org/2000/09/xmldsig#" attributeFormDefault="unqualified">
<xs:import namespace="http://www.w3.org/2000/09/xmldsig#" schemaLocation="xmldsig-core-schema.xsd"/>
<xs:element name="Info">
  <xs:complexType>
<xs:sequence>
      <xs:element name="Pan" type="xs:string"/>
      <xs:element name="Name" type="xs:string"/>
      <xs:element name="Email" type="xs:string"/>
      <xs:element name="City" type="xs:string"/>
      <xs:element name="State" type="xs:string"/>
      <xs:element name="AssessmentYear" type="xs:gYear"/>
      <xs:element name="MobileNo" type="xs:unsignedLong"/>
      <xs:element name="Income-Salary" type="xs:unsignedLong"/>
      <xs:element name="Income-Other" type="xs:unsignedLong"/>
      <xs:element name="TotalAmount" type="xs:unsignedLong"/>
      <xs:element ref="dsig:Signature" minOccurs="0" maxOccurs="1" />
</xs:sequence>
  </xs:complexType>
</xs:element>
</xs:schema>

和 XML：

<?xml version="1.0" ?>

Answer 3

您的 c2.xsd 仍然无效，请查看 ComplexType 定义：

<complexType
  id=ID
  name=NCName
  abstract=true|false
  mixed=true|false
  block=(#all|list of (extension|restriction))
  final=(#all|list of (extension|restriction))
  any attributes
 >

 (annotation?,(simpleContent|complexContent|((group|all|
 choice|sequence)?,((attribute|attributeGroup)*,anyAttribute?))))

</complexType>

属性必须在 group、all、choice 或 sequence 元素之后定义，因此更改顺序<xs:element name="Reference">以便先定义<xs:all>，然后再定义<xs:attribute>：

      <xs:element name="Reference">
         <xs:complexType>
           <xs:all>
           <xs:element name="Transforms">
             <xs:complexType>
               <xs:sequence>
                 <xs:element name="Transform" type="xs:string">
                   <xs:complexType>
                     <xs:attribute name="Algorithm" type="xs:string" use="required"/>
                   </xs:complexType>
                  </xs:element>
               </xs:sequence>
             </xs:complexType>
           </xs:element>
           <xs:element name="DigestMethod">
             <xs:complexType>
               <xs:attribute name="Algorithm" type="xs:string" use="required"/>
             </xs:complexType>
           </xs:element>
           <xs:element name="DigestValue" type="xs:hexBinary"/>
           </xs:all>
           <xs:attribute name="URI" type="xs:string"/>
         </xs:complexType>
        </xs:element>
