如何在Java中针对XSD 1.1验证XML？ [英] How to validate XML against XSD 1.1 in Java?

问题描述

用Java中的XML Schema 1.1验证XML文件的最佳方法是什么？

What is the best way to validate XML files against XML Schema 1.1 in Java?

我从这个教程并更改了工厂查找的行以使用XML Schema 1.1，如我所见这个代码示例来自 Xerces FAQ 。

I took the code from this tutorial and changed the line where it looks up the factory to use XML Schema 1.1 as I have seen in this code example from the Xerces FAQ.

这是我的代码：

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;

public class XSDValidator {
    private static void validateFile(File xmlFile, File xsdFile) throws SAXException, IOException
    {
        // 1. Lookup a factory for the W3C XML Schema language
        SchemaFactory factory = SchemaFactory.newInstance("http://www.w3.org/XML/XMLSchema/v1.1");
        // SchemaFactory factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);

        // 2. Compile the schema.
        File schemaLocation = xsdFile;
        Schema schema = factory.newSchema(schemaLocation);

        // 3. Get a validator from the schema.
        Validator validator = schema.newValidator();

        // 4. Parse the document you want to check.
        Source source = new StreamSource(xmlFile);

        // 5. Check the document
        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());
        }
    }
}

代码抛出此异常：

java.lang.IllegalArgumentException: No SchemaFactory that implements the schema language specified by: http://www.w3.org/XML/XMLSchema/v1.1 could be loaded

正如我所看到的，我的导入完全相同Xerces FAQ中的代码片段。我甚至试图将Xerces添加到我的Maven依赖项中，但这也没有帮助。

As I see it I have exactly the same imports as the code snippet in the Xerces FAQ. I even tried to add Xerces to my Maven dependencies but that didn't help either.

干杯：）

推荐答案

我认为您不能使用JAXP服务机制来搜索XSD 1.1处理器。以正常方式加载Saxon或Xerces，然后启用XSD 1.1处理。对于Saxon，这是使用

I don't think you can use the JAXP service mechanism to search for an XSD 1.1 processor. Load Saxon or Xerces in the normal way, and then enable XSD 1.1 processing. For Saxon this is done using

SchemaFactory.setProperty("http://saxon.sf.net/feature/xsd-version", "1.1")
