使用 ISO-8859-1 验证 XSD 架构

Question

我有一个XML。而这个 XML 我必须用 e XSD 来验证。 XSD 请求 ISO-8859-1 编码。

我已经尝试使用此代码，但它不起作用。看谁错了？

    public boolean validateXML(Document doc) throws ParserConfigurationException, IOException {

    XMLOutputter xmlOutput = new XMLOutputter();
    String xml = xmlOutput.outputString(doc);

    try {
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        factory.setValidating(true);
        factory.setNamespaceAware(true);

        final SchemaFactory sf = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);

        factory.setValidating(true);
        final Schema schema = sf.newSchema(new StreamSource(getClass().getResourceAsStream(SCHEMA_PATH)));
        factory.setSchema(schema);

        factory.setAttribute("http://java.sun.com/xml/jaxp/properties/schemaLanguage", "http://www.w3.org/2001/XMLSchema");
        DocumentBuilder builder = factory.newDocumentBuilder();

        InputSource is = new InputSource(xml);
        is.setEncoding("ISO-8859-1");

        builder.parse(is);
        return true;
    } catch (ParserConfigurationException pce) {
        throw pce;
    } catch (IOException io) {
        throw io;
    } catch (SAXException se) {
        return false;
    }
}

顶部来自 XSD

<?xml version='1.0' encoding='ISO-8859-1' ?>

按以下方式做:

    public class XMLUtils {

  private XMLUtils() {}

  // validate SAX and external XSD 
  public static boolean validateWithExtXSDUsingSAX(String xml, String xsd) 
  throws ParserConfigurationException, IOException 
  {
    try {
      SAXParserFactory factory = SAXParserFactory.newInstance();
      factory.setValidating(false); 
      factory.setNamespaceAware(true);

      SchemaFactory schemaFactory = SchemaFactory.newInstance("http://www.w3.org/2001/XMLSchema");
      SAXParser parser = null;
      try {
         factory.setSchema(schemaFactory.newSchema(new Source[] {new StreamSource( xsd )}));
         parser = factory.newSAXParser();
      }
      catch (SAXException se) {
        System.out.println("SCHEMA : " + se.getMessage());  // problem in the XSD itself
        return false;
      }

      XMLReader reader = parser.getXMLReader();
      reader.setErrorHandler(
          new ErrorHandler() {
            public void warning(SAXParseException e) throws SAXException {
              System.out.println("WARNING: " + e.getMessage()); // do nothing
            }

            public void error(SAXParseException e) throws SAXException {
              System.out.println("ERROR : " + e.getMessage());
              throw e;
            }

            public void fatalError(SAXParseException e) throws SAXException {
              System.out.println("FATAL : " + e.getMessage());
              throw e;
            }
          }
          );
      reader.parse(new InputSource(xml));
      return true;
    }    
    catch (ParserConfigurationException pce) {
      throw pce;
    } 
    catch (IOException io) {
      throw io;
    }
    catch (SAXException se){
      return false;
  }
}

public static void main (String args[]) throws Exception{ 
    System.out.println
        (XMLUtils.validateWithExtXSDUsingSAX
            ("c:/temp/YourXML.xml", "c:/temp/YourXSD.xsd"));

  }
}

output :(if it is validated) true

希望对你有所帮助..

我有方法验证XML。我将输出器设置为 "setEncoding("ISO-8859-1")"

为什么最后 XML 文件以

开头

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

方法验证XML

private void validateXML(Document doc) throws Exception {

    XMLOutputter xmlOutput = new XMLOutputter(Format.getPrettyFormat().setEncoding("ISO-8859-1"));

    String docStr = xmlOutput.outputString(doc);

    //InputStream inputStream = new ByteArrayInputStream(docStr.getBytes(Charset.forName("ISO-8859-1")));
    byte[] bytes = docStr.getBytes(Charset.forName("ISO-8859-1"));
    InputStream inputStream = new ByteArrayInputStream(bytes);

    Source xml = new StreamSource(inputStream);
    File xsdfile = new File(this.getClass().getClassLoader().getResource(SCHEMA_PATH).getFile());

    SchemaFactory schemaFactor = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
    Schema schema = schemaFactor.newSchema(xsdfile);


    Validator validator = schema.newValidator();

    validator.validate(xml);

}

使用 ISO-8859-1 验证 XSD 架构

Validate XSD Schema with ISO-8859-1

java

xml

validation

iso-8859-1
