        System.out.println("xsdFileName=" + xsdFileName);
        try {
            //创建默认的XML错误处理器 
            XMLErrorHandler errorHandler = new XMLErrorHandler();
            //获取基于 SAX 的解析器的实例 
            SAXParserFactory factory = SAXParserFactory.newInstance();
            //解析器在解析时验证 XML 内容。 
            factory.setValidating(true);

4.Note

1):<xsd:sequence>标签下面的元素在xml文件中顺序必须与xsd文件中的顺序一致

2):无序是怎么办，可以用<xsd:choice>；

3):在<xsd:complexType>标签中，<xsd:sequence>必须要写在<xsd:attribute>标签的前面
