					.newDocumentBuilder();
			Document document = parser.parse(new File("arq4.xml"));

			SchemaFactory factory = SchemaFactory
					.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);

			Source schemaFile = new StreamSource(new File("valida1.dtd"));
			Schema schema = factory.newSchema(schemaFile);

			Validator validator = schema.newValidator();

			validator.validate(new DOMSource(document));
