如何获取XSD1.1模式模型进行解析？

Question

在程序集的schemaLanguage后面是“http://www.w3.org/xml/xmlschema/v1.1”，newSchema()返回类型为{org.apache.xerces.jaxp.validation.simplexmlschema}的模式。我无法导入该类，错误是-org.apache.xerces.jaxp.validation.SimpleXMLSchema类型不可见

Example: <assert test="starts-with(@partnumber,../@partnumber)"/>

任何建议/帮助都会帮助我解决这个问题。谢了。

    try {

      SchemaFactory factory = SchemaFactory.newInstance(language);
      schema = factory.newSchema(new File(name));

官方的Xerces版本似乎还不支持XSD1.1。然而，以下Maven依赖关系对我来说很好：

    <dependency>
        <groupId>org.opengis.cite.xerces</groupId>
        <artifactId>xercesImpl-xsd11</artifactId>
        <version>2.12-beta-r1667115</version>
    </dependency>

这里有一些解析V1.1的示例代码。XSD：

import java.io.File;
import java.io.IOException;

import javax.xml.transform.Source;
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;

...

private static void validateFile(File xmlFile, File xsdFile) throws SAXException, IOException {
    SchemaFactory factory = SchemaFactory.newInstance("http://www.w3.org/XML/XMLSchema/v1.1");
    File schemaLocation = xsdFile;
    Schema schema = factory.newSchema(schemaLocation);
    Validator validator = schema.newValidator();
    Source source = new StreamSource(xmlFile);
    try
    {
        validator.validate(source);
        System.out.println(xmlFile.getName() + " is valid.");
    }
    catch (SAXException ex)
    {
        System.out.println(xmlFile.getName() + " is not valid because ");
        System.out.println(ex.getMessage());
    } }
