Writind Data to XML in XML Format

Question

Hi,
This is my First post in Sun Forums.
I m learning XML writing in Java.
I have searched on the Net but unable to find the proper XML writing Method using any API.
Please provide code for writing the XML in correct format with useful API.?
i m giving the Scenario of XML here:-
<?xml version="1.0" encoding="UTF-8"?>
<Data>
<Description>Description Addes</Description>
<Details>Details Added</Details>
</Data>
I want to Write this Data Using the Java using any API.
Also I want to append the Data while i m executing the XML for second time.
<?xml version="1.0" encoding="UTF-8"?>
<Data>
<Description>Description Addes</Description>
<Details>Details Added</Details>
</Data>
<Data>
<NewDescription>NewDescription Addes</NewDescription>
<NewDetails>NewDetails Added</NewDetails>
</Data>
I have also made 1 application using dom4j which write data to XML file but while i m appending the Data
for the Second time in the XML the same line repeatd <?xml version="1.0" encoding="UTF-8"?> in the XML.
So please guide me how to remove or delete this line while i m going for writing the XML again or Appending the Data Again..
Please provide some code or good Links or Solution for my Problem for writing the Simple XML format file and Appending the Data to the Same XML without including the <?xml version="1.0" encoding="UTF-8"?> this line
Again ?
?.

Hi,
I have Attached my Whole code in which the Same Line <?xml version="1.0" encoding="UTF-8"?> is appended while i m running this code second ,third ,fourth....n..times...
import java.util.logging.Level;
import java.util.logging.Logger;
import org.dom4j.Document;
import org.dom4j.DocumentHelper;
import org.dom4j.Element;
import org.dom4j.io.XMLWriter;
import org.dom4j.io.OutputFormat;
import java.io.*;
public class XMLWriting {
FileWriter out;
int i=1;
OutputFormat outformat;
XMLWriter writer;
public XMLWriting() {
public static void main(String s[]) {
System.out.println("In the Main Method::");
XMLWriting onj = new XMLWriting();
onj.createDocument();
System.out.println("In the Main Method::111111111111");
public void createDocument() {
try {
System.out.println("In the Main Method::22222222222");
out = new FileWriter("D:/foo3",true);
} catch (IOException ex) {
//Logger.getLogger(XMLWriting.class.getName()).log(Level.SEVERE, null, ex);
System.out.println("Exception Is in the CreateDocument Is::"+ex.getMessage());
Document document =DocumentHelper.createDocument();
Element root = document.addElement("root");
String Data="Data";
//Element testNode = root.addElement("Description");
Element author1 = root.addElement("Description").addText(Data);
Element author2 = root.addElement("Data").addText(" nimesh");
Element author3 = root.addElement("XMl").addText("Jignesh");
try {
//OutputFormat outformat =OutputFormat.createCompactFormat();
outformat = OutputFormat.createPrettyPrint();
writer= new XMLWriter(out,outformat);
writer.write(document);
writer.close();
} catch (Exception e) {
System.out.println("Exception Is ::"+e.getMessage());
e.printStackTrace();
OutPut after Executing Two Time:-
<?xml version="1.0" encoding="UTF-8"?>//same line appended twice
<root>
<Description>Data</Description>
<Data>nimesh</Data>
<XMl>Jignesh</XMl>
</root>
<?xml version="1.0" encoding="UTF-8"?>//same line appended twice
<root>
<NewDescription>NewData</NewDescription>
<NewData>Newnimesh</NewData>
<NewXMl>NewJignesh</NewXMl>
</root>
Please help me out in this ....If any modification is needed then correct my mistake and reply me with modified code ...I want this type of OutPut without Appending the <?xml version="1.0" encoding="UTF-8"?> this line in the XML file....
<?xml version="1.0" encoding="UTF-8"?>
<root>
<Description>Data</Description>
<Data>nimesh</Data>
<XMl>Jignesh</XMl>
</root>
<root>
<NewDescription>NewData</NewDescription>
<NewData>Newnimesh</NewData>
<NewXMl>NewJignesh</NewXMl>
</root>
