SAXParser for XSD 1.1 Validation

This section describes a tutorial example trying to use the Xerces2 SAXParser class included in JDK 1.7 to perform XSD 1.1 validation on an XML document. The program fails.

Now let's try to see if we make SAXValidatorJdk17.java program with XSD 1.1 by setting "http://www.w3.org/XML/XMLSchema/v1.1" as the schema language property:

class SAXValidatorJdk17Xsd11 {
   public static void main(String[] args) {
      String schemaFeature 
         = "http://apache.org/xml/features/validation/schema";
      try {
         File x = new File(args[0]);
         String schemaLocation = args[1];
         SAXParserFactory f = SAXParserFactory.newInstance();

         SAXParser p = f.newSAXParser();


         DefaultHandler h = new MyErrorHandler();
      } catch (ParserConfigurationException e) {
      } catch (SAXException e) {
      } catch (IOException e) {
   private static class MyErrorHandler extends DefaultHandler {
      public void warning(SAXParseException e) throws SAXException {
         System.out.println("Warning: "); 
      public void error(SAXParseException e) throws SAXException {
         System.out.println("Error: "); 
      public void fatalError(SAXParseException e) throws SAXException {
         System.out.println("Fattal error: "); 
      private void printInfo(SAXParseException e) {
         System.out.println("   Public ID: "+e.getPublicId());
         System.out.println("   System ID: "+e.getSystemId());
         System.out.println("   Line number: "+e.getLineNumber());
         System.out.println("   Column number: "+e.getColumnNumber());
         System.out.println("   Message: "+e.getMessage());

Running it with the "Xerces2 2.11.0 (XML Schema 1.1) (Beta)" version:

c:\Progra~1\Java\jdk1.7.0_07\bin\javac SAXValidatorJdk17Xsd11.java

   -cp ".;c:\local\xerces-2_11_0-xml-schema-1.1-beta\xercesImpl.jar;
   SAXValidatorJdk17Xsd11 dictionary_invalid_xsd.xml dictionary.xsd

org.xml.sax.SAXNotSupportedException: The specified schema language 
   is not supported.

Too bad, the SAXParse object created with the default configuration does not recognize the XSD 1.1 URI: http://www.w3.org/XML/XMLSchema/v1.1.
