通过 DOM4J 方式生成 XML 文档

1.引入dom4j jar包

2.代码

　　　　Document document = DocumentHelper.createDocument();
        Element ele = document.addElement("tree");
        ele.addAttribute("id", "0");
        Element e1 = ele.addElement("name");
        e1.setText("名称");
        
        OutputFormat format = OutputFormat.createPrettyPrint();//输出格式
        format.setEncoding("GBK");//设置编码
        
        try {
            XMLWriter writer = new XMLWriter(new FileOutputStream(new File("ressTest.xml")),format);
            writer.setEscapeText(false);//设置是否转义，默认true转义
            writer.write(document);
            writer.close();
        }catch (IOException e) {
            e.printStackTrace();
        }

3.结果

<?xml version="1.0" encoding="GBK"?>

<tree id="0">
  <name>名称</name>
</tree>
