Hi!

Finally, I found a way to get it work. By setting the namespace-feature to
true and setting the XSD definition with the
http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation
property, the parser actually validates using my schema defintion.

Thanx for your efforts.

greetings
Heiner

Have you tried turning on namespace? (SAXParserFactory#setNamespaceAware)

Hi there!

I'm still unable to validate my xml file against an XSD. Here ist the code,
I use to load the file via SAX, using XERCES 2.0 (JRE1.3.1):

    private static final String FLAG_VALIDATE =
"http://xml.org/sax/features/validation";;
    private static final String FLAG_SCHEMA =
"http://apache.org/xml/features/validation/schema";;

    private SAXParserFactory factory = null;
    private org.xml.sax.SAXParser saxParser = null;

             ...
        factory = SAXParserFactory.newInstance();
             ...
        saxParser = factory.newSAXParser();
             ...
             saxParser.getXMLReader().setFeature(FLAG_VALIDATE, true);
             saxParser.getXMLReader().setFeature(FLAG_SCHEMA, true);
             saxParser.parse(new File(file), this);
             ...

This always gives me an error saying "cvc-elt.1: Cannot find the
declaration
of element 'whatever'".

Since then, I've tried to use an EntityResolver for loading the XSD. I've
started with writing a little test code for the EntryResolver like this:

public class SAXEntityResolver implements EntityResolver {

        public InputSource resolveEntity(String publicID, String systemID)
throws SAXException, IOException {
            System.out.println(publicID+", "+systemID);
            return null;
        }

}

...

    private static final String FLAG_VALIDATE =
"http://xml.org/sax/features/validation";;
    private static final String FLAG_SCHEMA =
"http://apache.org/xml/features/validation/schema";;

    private SAXParserFactory factory = null;
    private SAXParser saxParser = null;

             ...
        factory = SAXParserFactory.newInstance();
             ...
        saxParser = factory.newSAXParser();
             ...
             saxParser.getXMLReader().setFeature(FLAG_VALIDATE, true);
             saxParser.getXMLReader().setFeature(FLAG_SCHEMA, true);
             saxParser.getXMLReader().setEntityResolver(new
SAXEntityResolver());
             saxParser.parse(new File(file), this);
             ...

In result, my programm still reads the xml file with the same error as
before. The println() in the EntityResolver is never reached.

I woulde really appreciate any help on this. Next on schedule is testing
and
I'm still unable to validate the xml file. Btw., loading the file with any
other XML/XSD aware application works fine.

regards
Heiner
