如何使用XSD验证XML呢?

实现思路:
    使用SchemaFactory中的相关类
	对xml进行验证

static boolean validateXSD(InputStream xml, InputStream xsd)
{
    try
    {
        SchemaFactory factory = 
          SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
        Schema schema = factory.newSchema(new StreamSource(xsd));
        Validator validator = schema.newValidator();
        validator.validate(new StreamSource(xml));
        return true;
    }
    catch(Exception ex)
    {
        return false;
    }
}
