how to write xml file in jva?

  

import java.io.File;

import javax.xml.parsers.DocumentBuilder;

import javax.xml.parsers.DocumentBuilderFactory;

import javax.xml.parsers.ParserConfigurationException;

import javax.xml.transform.Transformer;

import javax.xml.transform.TransformerException;

import javax.xml.transform.TransformerFactory;

import javax.xml.transform.dom.DOMSource;

import javax.xml.transform.stream.StreamResult;

import org.w3c.dom.Attr;

import org.w3c.dom.Document;

import org.w3c.dom.Element;

public class XmlApp {

public static void main(String argv[]) {

try {

DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();

DocumentBuilder docBuilder = docFactory.newDocumentBuilder();

// root elements

Document doc = docBuilder.newDocument();

Element rootElement = doc.createElement("college");

doc.appendChild(rootElement);

// student element

Element st = doc.createElement("Student");

rootElement.appendChild(st);

// set attribute to st element

Attr attr = doc.createAttribute("stundentId");

attr.setValue("1");

st.setAttributeNode(attr);

// shortest way

// st.setAttribute("studentid", "1");

// studentname element

Element sname = doc.createElement("studentName");

sname.appendChild(doc.createTextNode("sunny"));

st.appendChild(sname);

// address element

Element address = doc.createElement("address");

address.appendChild(doc.createTextNode("hyderabad"));

st.appendChild(address);

// email elements

Element email = doc.createElement("email");

email.appendChild(doc.createTextNode("sunny@gmail.com"));

st.appendChild(email);

// phone number elements

Element phno = doc.createElement("phoneNumber");

phno.appendChild(doc.createTextNode("9080706050"));

st.appendChild(phno);

// write the content into xml file and store the file in some location.

TransformerFactory transformerFactory = TransformerFactory.newInstance();

Transformer transformer = transformerFactory.newTransformer();

DOMSource source = new DOMSource(doc);

StreamResult result = new StreamResult(new File("E:\\StudentFile.xml"));

transformer.transform(source, result);

System.out.println("File saved!");

} catch (ParserConfigurationException pce) {

pce.printStackTrace();

} catch (TransformerException tfe) {

tfe.printStackTrace();

}

}

}

Output for the above program is:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

<college>

<Student stundentId="1">

<studentName>sunny</studentName>

<address>hyderabad</address>

<email>sunny@gmail.com</email>

<phoneNumber>9080706050</phoneNumber>

</Student></college>
