共有三种方法，分别使用了JDK, xerces.jar或jdom.jar。

}
//Approach 1:only use the JDK 1.4
//In this case, I handle the Chinese correctly with the TransFormer.setOutputProperty()
//These packages are necessary:
//org.w3c.dom
//javax.xml.parsers
//javax.xml.transform
//javax.xml.transform.dom
//javax.xml.transform.stream
public DOMTest()
{
try
{
//code to create a new DOM document goes here...
javax.xml.parsers.DocumentBuilder builder =
javax.xml.parsers.DocumentBuilderFactory.newInstance().newDocumentBuilder();
org.w3c.dom.Document doc = builder.newDocument();
//Add some elements here...
org.w3c.dom.Element root = doc.createElement("老师");
org.w3c.dom.Element wang = doc.createElement("王");
wang.appendChild(doc.createTextNode("我是王老师"));
root.appendChild(wang);
doc.appendChild(root);
//code to save goes here...
javax.xml.transform.Transformer transformer =
javax.xml.transform.TransformerFactory.newInstance().newTransformer();
//Notice this first sentence below, which resolves the problem of Chinese
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());
}
}
//Approach 2:use Xerces additionally. The xerces.jar must have been in
//your CLASSPATH
//In this case, Chinese characters can be handled successfully.
//These packages are necessary:
//org.w3c.dom
//org.apache.xerces.parsers
//org.apache.xml.serialize
////public DOMTest()
////{
////try
////{
//////code to parse an existed XML file goes here...
////org.apache.xerces.parsers.DOMParser parser =
////new org.apache.xerces.parsers.DOMParser();
////parser.parse(inFile);
////org.w3c.dom.Document.doc = parser.getDocument();
////
//////code to save goes here...
////FileWriter writer = new FileWriter(outFile);
//////Pay attention to the OutputFormat constructor, which set the GB2312
////org.apache.xml.serialize.OutputFormat outputFormat =
////new org.apache.xml.serialize.OutputFormat(doc, "GB2312", true);
////
////org.apache.xml.serialize.XMLSerializer serializer =
////new org.apache.xml.serialize.XMLSerializer(writer, outputFormat);
////serializer.serialize(doc);
////writer.close();
////}
////catch (Exception e)
////{
////System.out.println (e.getMessage());
////}
////}
//Approach 3: use the JDOM package, and this is the simplest one. Additionally,
//the jdom.jar must have been in your CLASSPATH
//These package are necessary:
//org.jdom
//org.jdom.input
//org.jdom.output
////public DOMTest()
////{
////try
////{
//////code to parse an existed XML file goes here...
////org.jdom.input.SAXBuilder builder = new org.jdom.input.SAXBuilder();
////org.jdom.Document doc = builder.build(inFile);
////
//////code to save goes here...
////FileWriter writer = new FileWriter(outFile);
////
////org.jdom.output.XMLOutputter outputter =
////new org.jdom.output.XMLOutputter("", true, "GB2312");
////outputter.output(doc, writer);
////writer.close();
////}
////catch (Exception e)
////{
////System.out.println (e.getMessage());
////}
////}
