Question

I m 试图将我XML的档案从XSD的档案中查实,并附有以下代码:

        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());
        }

我把我的XSD文件上载到这里,以显示:。

但是,当我执行我的法典时,我发现这一错误:

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

问题是什么,我如何解决这一问题?

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). More on this in XSD Primer: http://www.w3.org/TR/2004/REC-xmlschema-0-20041028/#Globals
