• 模擬輸出一組資訊資料
• 用陣列模擬要儲存的資料

        //儲存資訊的陣列
        int[] id = new int[]{1,2,3};
        String[] names = new String[]{"maoshu","lose","Houce"};
        String[] sexs = new String[]{"男","女","男"};

• 想要在xml檔案中儲存三個人的基本資訊,id,姓名,性別,輸出的xml檔案大致為以下格式

<people>
	<member>
		<
 
name id=1>maoshu</name>
		<sex>男</sex>
	</member>

	...
	
</people>

• 建立一個TestDOM4JOut,java類進行xml輸出,將DOM資料輸出到本地磁碟中"e:dom4jOut.xml"檔案中

  public static void main(String[] args)throws Exception{
        //儲存資訊的陣列
        int[] id = new int[]{1,2,3};
        String[]
 
 names = new String[]{"maoshu","lose","Houce"};
        String[] sexs = new String[]{"男","女","男"};

        //建立xml文件
        Document xmlDoc = DocumentHelper.createDocument();
        //建立文件下子元素"people"
        Element peopleEle = xmlDoc.addElement("people");

        //迴圈建立三個people元素下的三個member子元素
        for
 
 (int i = 0; i < id.length; i++) {
            Element memberEle = peopleEle.addElement("member");
            //設定member元素的id屬性
            memberEle.addAttribute("id",String.valueOf(id[i]));
            //建立member元素熙的2個子元素,並設定子元素中的內容
            memberEle.addElement("name").setText(names[i]);
            memberEle.addElement("sex").setText(sexs[i]);
        }

        //設定xml資料輸出格式
        OutputFormat out = OutputFormat.createPrettyPrint();
        out.setEncoding("UTF-8");
        //指定輸出檔案
        File file = new File("e:"+ File.separator+"dom4j.xml");
        XMLWriter xmlWriter =new XMLWriter(new FileOutputStream(file),out);
        xmlWriter.write(xmlDoc);
    }
