Dom4j创建Xml


备注：放入dom4j-2.1.1.jar包

package Xml;

import java.io.IOException;
import java.io.StringWriter;

import org.dom4j.Document;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;
import org.dom4j.io.OutputFormat;
import org.dom4j.io.XMLWriter;

public class XmlTest {
    public XmlTest() {  
        // TODO Auto-generated constructor stub  
    }  
    public String createXML(int i){  
        String strXML = null;  
        Document document = DocumentHelper.createDocument();  
        // 创建根节点并添加进文档  
        Element root = document.addElement("persons");  
        for(int j=0;j<i;j++){  
        Element person = root.addElement("person");  
        person.addAttribute("id", "100"+i).addAttribute("location", "中原"+i+"区");  
        Element name = person.addElement("name");  
        name.setText("小明"+i);  
        Element age = person.addElement("age");  
        age.addText("1"+i); //值！！  
        }  
        //--------  
        StringWriter strWtr = new StringWriter();  
        OutputFormat format = OutputFormat.createPrettyPrint();//Format格式！！  
        format.setEncoding("UTF-8");      
        XMLWriter xmlWriter =new XMLWriter(strWtr, format);  
        try {  
            xmlWriter.write(document);  
        } catch (IOException e1) {  
            // TODO Auto-generated catch block  
            e1.printStackTrace();  
        }  
        strXML = strWtr.toString();  
        return strXML;  
   }  
    public static void main(String[] args) {  
        XmlTest test = new XmlTest();  
       
        String xmlStr = test.createXML(4);  
        System.out.println(xmlStr);  
    }  
}
输出结果：
<?xml version="1.0" encoding="UTF-8"?>
