DOM4J生成XML
创建Document 对象,代表整个 XML 文档
//创建Document 对象,代表整个 xml文档 Document document = DocumentHelper.createDocument();
创建根节点
//创建根节点 Element school = document.addElement("school");
创建子节点以及子节点的属性和属性值
//创建子节点 Element student = school.addElement("student"); //子节点的属性 student.addAttribute("id", "1");
创建 student下的子节点以及添加内容
//创建 student下的子节点 Element name = student.addElement("name"); //添加内容 name.setText("张三");
自动格式话 XML 文件
//自动格式化xml 文件 OutputFormat format = OutputFormat.createPrettyPrint();
创建 XML 文件
//创建 XML 文件 File file =new File("DOM4JXML.xml"); XMLWriter writer = new XMLWriter(new FileOutputStream(file),format); //特殊字符,是否转义,默认为true writer.setEscapeText(false); writer.write(document); writer.close();
运行结果:
<?xml version="1.0" encoding="UTF-8"?> <school> <student id="1"> <name>张三</name> </student> </scho
