用 jdom 解析 xml 文件時如何解決中文問題 ? 如何解析 ?

package test;
import java.io.*;
public class DOMTest
{
private String inFile = "c://people.xml";
private String outFile = "c://people.xml";
public static void main(String args[])
{
new DOMTest();
}
public DOMTest()
{
try
{
javax.xml.parsers.DocumentBuilder builder =

javax.xml.parsers.DocumentBuilderFactory.newInstance().newDocumentBuilder();
org.w3c.dom.Document doc = builder.newDocument();
org.w3c.dom.Element root = doc.createElement(" 老師 ");
org.w3c.dom.Element wang = doc.createElement(" 王 ");
org.w3c.dom.Element liu = doc.createElement(" 劉 ");
wang.appendChild(doc.createTextNode(" 我是王老師 "));
root.appendChild(wang);
doc.appendChild(root);
javax.xml.transform.Transformer transformer =
javax.xml.transform.TransformerFactory.newInstance().newTransformer();
transformer.setOutputProperty(javax.xml.transform.OutputKeys.ENCODING, "gb2312");
transformer.setOutputProperty(javax.xml.transform.OutputKeys.INDENT, "yes");

transformer.transform(new javax.xml.transform.dom.DOMSource(doc),
new

javax.xml.transform.stream.StreamResult(outFile));
}
catch (Exception e)
{
System.out.println (e.getMessage());
}
}
}
