如何使用Xerces2-j验证包含目录的xml文件

Question

我正在尝试使用oasis目录验证xml文件。我需要的是提供xml文件的路径和包含xsd的目录的路径作为输入，并将验证(true或error message)作为输出。

到目前为止，我所做的是：

    File schemaFile = new File("personal.xsd"); // etc.
    Source xmlFile = new StreamSource(new File("personal.xml"));
    SchemaFactory schemaFactory = SchemaFactory.newInstance("http://www.w3.org/XML/XMLSchema/v1.1"); // we need to validate with v1.1


    try {
        Schema schema = schemaFactory.newSchema(schemaFile);
        Validator validator = schema.newValidator();
        validator.validate(xmlFile);
        System.out.println(xmlFile.getSystemId() + " is valid");
    } catch (SAXException e) {
        System.out.println(xmlFile.getSystemId() + " is NOT valid reason:" + e);
    } catch (IOException e) {
        e.printStackTrace();
    }

因此，到目前为止，它是有效的。

问题是添加目录。我找到了一些代码示例，但它不起作用：

Source xmlFile = new StreamSource(new File("personal.xml"));
String [] catalogs =  {"file:///catalog.xml"};
SchemaFactory schemaFactory = SchemaFactory.newInstance("http://www.w3.org/XML/XMLSchema/v1.1");
    try {
        
        XMLCatalogResolver resolver = new XMLCatalogResolver();
        resolver.setPreferPublic(true);
        resolver.setCatalogList(catalogs);
        schemaFactory.setResourceResolver(resolver);
        
        Schema schema = schemaFactory.newSchema();
        Validator validator = schema.newValidator();
        validator.validate(xmlFile);

}

最后，找不到xsd，验证失败。

有人能给我解释一下我哪里做错了吗？我觉得这应该很简单，但我遗漏了一些东西。

谢谢。

经过两周的研究，我的结论是

我从来没有用Xerces-2j做到这一点。您可以使用JRE (javaSE-1.8)中的xerces来完成此任务，下面是如何完成此任务的方法。

import java.io.File;
import java.io.StringWriter;

import java.net.URL;

//import javax.xml.validation.SchemaFactory;

import java.net.URI;
import java.net.URISyntaxException;

import javax.xml.XMLConstants;
//import javax.xml.catalog.CatalogFeatures;
import javax.xml.transform.stream.StreamSource;
import javax.xml.transform.stream.StreamResult;
import javax.xml.validation.SchemaFactory;
import javax.xml.validation.Schema;
import javax.xml.validation.Validator;

import org.xml.sax.ErrorHandler;
import org.xml.sax.SAXException;
import org.xml.sax.SAXParseException;

public class Foo
{
    private static int errorCount = 0;

    public static void main(String[] args)
    {
        final String  catalogFile = "javax.xml.catalog.files";//CatalogFeatures.Feature.FILES.getPropertyName();
        final String  catalogPath = "catalog.xml";

        final ClassLoader  classLoader = Foo.class.getClassLoader();
        try
        {
            final URL  catalogUrl = classLoader.getResource(catalogPath);
            final URI  catalog = catalogUrl.toURI();

            if (catalog != null)
            {
                System.out.println("catalog : "+ catalogFile);
                SchemaFactory  schemaFactory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
//              SchemaFactory schemaFactory = SchemaFactory.newInstance("http://www.w3.org/XML/XMLSchema/v1.1");
                Schema  schema = schemaFactory.newSchema();

                StreamSource  source = new StreamSource(new File("personal.xml"));
                Validator  validator = schema.newValidator();
                validator.setProperty(catalogFile, catalog.toString());
                validator.setErrorHandler(new MyErrorHandler());
                StringWriter  writer = new StringWriter();
                StreamResult  result = new StreamResult(writer);
                validator.validate(source, result);

                System.out.println(writer);
            }
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
    }


    private static class MyErrorHandler implements ErrorHandler {
        public void warning(SAXParseException e) throws SAXException {
            System.out.println("Warning: ");
            printException(e);
        }
        public void error(SAXParseException e) throws SAXException {
            System.out.println("Error: ");
            printException(e);
        }
        public void fatalError(SAXParseException e) throws SAXException {
            System.out.println("Fattal error: ");
            printException(e);
        }
        private void printException(SAXParseException e) {
            errorCount++;
            System.out.println("   Line number: "+e.getLineNumber());
            System.out.println("   Column number: "+e.getColumnNumber());
            System.out.println("   Message: "+e.getMessage());
            System.out.println();
        }
    }
}

如果您想使用xerces-2J，请使用GL
