Hi,

You can use the Transformer class:

Transformer tFormer = TransformerFactory.newInstance().newTransformer();

For transforming the Document object into string.

XML file:

<?xml version = "1.0" ?>
<accounts>
    <account>
    <id>454457858778</id>
    <name>Dinesh</name>
    </account>
</accounts>

Java code:

import java.io.*;
import javax.xml.parsers.*;
import org.w3c.dom.*;
import org.xml.sax.*;
import javax.xml.transform.*; 
import javax.xml.transform.dom.DOMSource; 
import javax.xml.transform.stream.StreamResult;

public class XMLtoString{
  static public void main(String[] args){
    try{
      BufferedReader bf = new BufferedReader(new InputStreamReader(System.in));


        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder builder = factory.newDocumentBuilder();
        Document doc = builder.parse("1.xml");
        StringWriter stringWriter = new StringWriter(); 
        Transformer transformer = TransformerFactory.newInstance().newTransformer(); 
        transformer.transform(new DOMSource(doc), new StreamResult(stringWriter)); 
        String strFileContent = stringWriter.toString(); //This is string data of xml file
        System.out.println(strFileContent);

    }
    catch (Exception e){
      e.getMessage();
    }
  }
}

Thanks
