使用dom4j来生成XML文件

package io.xml;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStreamWriter;
import java.io.UnsupportedEncodingException;

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

// 由java对像生成XML文件
public class XMLDemo
{
public static void main(String[] args)
{
Document document = DocumentHelper.createDocument();

Element root = document.addElement("root");

Element students = root.addElement("students");

File file = new File("F:\\temp\\test.xml");
if (file.exists())
{
file.delete();
}
Student[] stu = new Student[5];
for (int i=0; i<5; i++)
{
stu[i] = new Student("name"+i, "id"+i, i*100);
}
try
{
for (int j=0; j<stu.length; j++)
{
Element stuElement = students.addElement("student");
stuElement.addElement("name").addText(stu[j].getName());
stuElement.addElement("id").addText(stu[j].getId());
stuElement.addElement("height").addText(String.valueOf(stu[j].getHeight()));
}

FileOutputStream fileStream = new FileOutputStream(file);
OutputStreamWriter outputStreamWriter = new OutputStreamWriter(fileStream, "UTF-8");

OutputFormat format = new OutputFormat();

format.setIndent(true);/// 缩排
format.setIndent(" "); // 缩排长度
format.setNewlines(true);// 折行

XMLWriter writer = new XMLWriter(outputStreamWriter, format);

writer.write(document);
outputStreamWriter.close();
fileStream.close();

writer.close();
System.out.println("success....");
}
catch (UnsupportedEncodingException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (FileNotFoundException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}

}
==================
生成的结果如下;
<?xml version="1.0" encoding="UTF-8"?>

<root>
<students>
<student>
<name>name0</name>
<id>id0</id>
<height>0</height>
</student>
<student>
<name>name1</name>
<id>id1</id>
<height>100</height>
</student>
<student>
<name>name2</name>
<id>id2</id>
<height>200</height>
</student>
<student>
<name>name3</name>
<id>id3</id>
<height>300</height>
</student>
<student>
<name>name4</name>
<id>id4</id>
<height>400</height>
</student>
</students>
</root>
