Question

   Below is the code 


import java.io.File;
    import java.io.IOException;
 import javax.xml.XMLConstants;
  import javax.xml.transform.stream.StreamSource;
  import javax.xml.validation.Schema;
 import javax.xml.validation.SchemaFactory;
          import javax.xml.validation.Validator;

    import org.xml.sax.SAXException;


 public class XMLValidation {

public static void main(String[] args) {

    System.out.println("request.xml validates agains xsd "+validateXMLSchema("request.xsd",  "request.xml"));
  }

public static boolean validateXMLSchema(String xsdPath, String xmlPath){

    try {
        SchemaFactory factory = 
                SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
        Schema schema;
        try {
            schema = factory.newSchema(new File(xsdPath));
             Validator validator = schema.newValidator();
                validator.validate(new StreamSource(new File(xmlPath)));
        } catch (SAXException e) {

            // TODO Auto-generated catch block
            e.printStackTrace();
            return false;
        }

    } 
    catch (IOException e) {
        System.out.println("Exception: "+e.getMessage());

    }
    return true;
}

以下是我针对请求xml验证并请求xsd时出现的错误：

您能帮我解决一下我的代码中需要进行哪些更改，以便在我的XSD中添加我不能对XSD进行任何更改，因为它是标准的，而且Soap：env不存在于请求XSD中但存在于请求XML中，因此在验证时它表示标签丢失。

您有两种选择：

在验证程序可用的模式中包含soap模式（为了进行模式验证，您必须提供所有相关模式）
从有效负载中剥离soap包装器元素，仅验证有效负载（假设您的架构仅适用于有效负载）。您可以使用引用有效负载DOMSource而不是Element的{{1}}。

无法解析org.xml.sax.SAXParseException：cvc-elt.1：找不到元素的声明＆＃39; soapenv：Envelope＆＃39;
