使用 JDOM 使用 xsd 验证 xml

Question

您好，我正在尝试使用 JDOM 验证带有 xsd 的 xml。 这是我的验证代码：-

public class jdom1 {

    public static void main(String[] args) throws JDOMException, IOException {

        // TODO Auto-generated method stub
        File xsdfile = new File("file.xsd");
        XMLReaderJDOMFactory schemafac = new XMLReaderXSDFactory(xsdfile);
        SAXBuilder builder = new SAXBuilder(schemafac);
        Document doc =  builder.build(new File("file.xml"));
        Element root = doc.getRootElement();
        for(Element testCase : root.getChildren()){
            //Code

    }

}

我的文件.xml :-

<?xml version="1.0" encoding="UTF-8"?>


<document>
 <testCaseDataName>
  <id>1</id >
  <testCaseName>Edit</testCaseName >
  <expectedResult>true</expectedResult >

 </testCaseDataName>
 <testCaseDataName>
  <id>2</id >
  <testCaseName>add</testCaseName >
  <expectedResult>false</expectedResult>
  <parameter>
    <key>featues</key >
    <value>w,f</value>
    </parameter>
 </testCaseDataName>

  <testCaseDataName>
  <id>3</id >
  <testCaseName>delete</testCaseName >
  <expectedResult>duplicate</expectedResult>
  <parameter>
    <key>projectType</key >
    <value>new</value>
    <key>Name</key >
    <value>mashnew</value>
    <key>status</key >
    <value>ACTIVE</value>
    <key>canOrder</key >
    <value>Yes</value>
    </parameter>
 </testCaseDataName>
 </document>

我的文件.xsd :-

<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema"
    targetNamespace="http://www.example.org/ACL"
    xmlns:tns="http://www.example.org/ACL"
    elementFormDefault="qualified">
    <include schemaLocation=""></include>
    <element name="document">
    <complexType>
      <sequence>
    <element name="testCaseDataName">
     <complexType>
      <sequence>
        <element name ="id" type ="ID" ></element>
        <element name ="testCaseName" type ="string" ></element>
        <element name = "expectedResult" type="string"></element>
        <element name = "parameter" minOccurs="0">
        <complexType>
            <sequence>
                <element name="key" type ="string" maxOccurs="1"></element>
                <element name="value" type="string" maxOccurs="unbounded"></element>
            </sequence>
        </complexType>
        </element>
        </sequence>
     </complexType>
    </element>
    </sequence>
    </complexType>
    </element>
</schema>

当我运行此代码时，我收到以下错误。谁能帮我解决这个问题。

这是进行验证的方法，请检查您的代码

SchemaFactory schemafac =
     SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
     Schema schema = schemafac.newSchema(new File("myschema.xsd"));
     XMLReaderJDOMFactory factory = new XMLReaderSchemaFactory(schema);
     SAXBuilder sb = new SAXBuilder(factory);
     Document doc = sb.build(new File("file.xml"));

使用下面的架构

<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="document">
    <xs:complexType>
      <xs:sequence>
        <xs:element name="testCaseDataName" maxOccurs="unbounded" minOccurs="0">
          <xs:complexType>
            <xs:sequence>
              <xs:element type="xs:byte" name="id"/>
              <xs:element type="xs:string" name="testCaseName"/>
              <xs:element type="xs:string" name="expectedResult"/>
              <xs:element name="parameter" minOccurs="0">
                <xs:complexType>
                  <xs:choice maxOccurs="unbounded" minOccurs="0">
                    <xs:element type="xs:string" name="key"/>
                    <xs:element type="xs:string" name="value"/>
                  </xs:choice>
                </xs:complexType>
              </xs:element>
            </xs:sequence>
          </xs:complexType>
        </xs:element>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>

我的架构错误。使用此http://www.freeformatter.com/xsd-generator.html 生成模式并且验证工作正常。谢谢
