Question

I’m trying to validate my XML files from given XSD file with the following code,

        Source xmlFile = new StreamSource(fXmlFile);
        SchemaFactory schemaFactory = SchemaFactory
        .newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
        Schema schema = schemaFactory.newSchema(new File("presentation.xsd"));
        Validator validator = schema.newValidator();
        try {
            validator.validate(xmlFile);
            System.out.println(xmlFile.getSystemId() + " is valid");
        } catch (SAXException e) {
            System.out.println(xmlFile.getSystemId() + " is NOT valid");
            System.out.println("Reason: " + e.getLocalizedMessage());
        }

And I uploaded my XSD file to here to show you: http://orhancanceylan.com/stack/presentation.xsd

But when I run my code, I get this error:

org.xml.sax.SAXParseException: s4s-att-not-allowed: Attribute 'maxOccurs' cannot appear in element 'element'.

What’s the problem, how should I solve it ?

Answer 1

You have an error in your schema, global presentation element cannot have constraints ( maxOccurs=”1″ minOccurs=”1″), you’d need to remove them (it does not make sense to have min/max for global elements, those constraints makes sense in context of other elements).
