JDOM(1.0)的初次接触

JDOM(1.0)的初次接触

一.源代码：

import org.jdom.Element;                 //代表元素
import org.jdom.Attribute;               //代表元素的属性
import org.jdom.Document;                //代表整个XML文档
import org.jdom.Comment;                 //注释
import org.jdom.output.XMLOutputter;     //输出
import org.jdom.output.Format;           //输出的格式
import java.io.FileWriter;               //  :)

public class JDomTest {

	public static void main(String[] args) throws Exception{

		Element root=new Element("人员信息");
		Document document=new Document(root);    //建立新XML文档，并以根元素初始化

		root.addContent(new Comment("新进公司职员")); //建立新元素，并将新元素作为根元素的内容.
		root.setAttribute(new Attribute("单位","XXXX软件公司"));
		root.addContent(new Element("姓名").addContent("XYZ"));
		root.addContent(new Element("年龄").addContent("23")
		                                   .setAttribute("体形","适中"));
		root.addContent(new Element("性别").addContent("男"));
		root.addContent(new Element("身高").addContent("green"));
		root.addContent(new Element("体重").addContent("75KG"));


		//output
		Format format=Format.getPrettyFormat(); //静态方法，产生两个空格的缩进格式
		format.setIndent("    ");               //变成四个空格的缩进格式,用四个空格字符作参数
		format.setEncoding("gb2312");           //设置编码格式

		XMLOutputter out=new XMLOutputter(format);  
		out.output(document,System.out);	//输出到控制台

		FileWriter writer=new FileWriter("./jdomtest.xml");
		out.output(document,writer);            //输出到文件
	}
}


二.说明：
以上代码根据网上文章所写，总体感觉JDOM使用起来，比SAX，DOM要顺手的多（仅为个人观点）。

三.程序输出


<人员信息 单位="XXXX软件公司">
    
    <姓名>XYZ
    <年龄 体形="适中">23
    <性别>男
    <身高>green
    <体重>75KG
