Besides the tutorials mentioned already, here is a simple example that uses javax.xml.transformand org.w3c.dompackages:
除了已经提到的教程，这里还有一个简单的例子，使用javax.xml.transform和org.w3c.dom包：
import java.io.*;
import javax.xml.transform.*;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
import org.w3c.dom.*;
import com.sun.org.apache.xerces.internal.dom.DocumentImpl;
public class XML {
public static void main(String[] args) {
XML xml = new XML();
xml.makeFile();
}
public void makeFile() {
Node item = null;
Document xmlDoc = new DocumentImpl();
Element root = xmlDoc.createElement("booking");
item = xmlDoc.createElement("bookingID");
item.appendChild(xmlDoc.createTextNode("115"));
root.appendChild(item);
xmlDoc.appendChild(root);
try {
Source source = new DOMSource(xmlDoc);
File xmlFile = new File("yourFile.xml");
StreamResult result = new StreamResult(new OutputStreamWriter(
new FileOutputStream(xmlFile), "ISO-8859-1"));
Transformer xformer = TransformerFactory.newInstance().newTransformer();
xformer.transform(source, result);
} catch(Exception e) {
e.printStackTrace();
}
}
}
