JSON To XML Conversion

Hi friends,

I would like to share converting JOSN to XML format.

XML: 

• XML (Extensible Markup Language) is a mark-up language that defines the set of rules for encoding document in Human &Machine readable format.
• XML mainly emphasizes on Simplicity, Generality and Usability over the Internet. 
• XML is a textual data format with strong support for all the languages of the World.

JSON:

• JSON (JavaScript Object Notation) is a text-based open standard designed for Human-Readable data interchange.
• Even JSON is javaScript specific, it is language-independent with parsers available for many languages.
• JSON format is often used over network connection for serializing and transmitting structured data .

On keeping Pros and Cons of them a-part, this is the scenario which is very often needed for developing Applications (Mainly in Web environment).

Pre-Requisites:

I used net.sf.json-lib for JSON support. You can download from here.

Json-lib should contain the below dependencies in classpath:

• commons-lang
• commons-beanutils
• commons-collections
• commons-logging
• ezmorph

Below is code for Converting JSON to XML format:

package testapp;
import java.io.InputStream;
import java.net.URL;
import net.sf.json.JSON;
import net.sf.json.xml.XMLSerializer;
import org.apache.commons.io.IOUtils;
/**
 * @author naveen.k
 */
public class JsonToXMLConverter {
    private URL url = null;
    private InputStream inputStream = null;    
    public void getJsonfromXml() {
        try{
            url = JsonToXMLConverter.class.getClassLoader().getResource("sample.txt");
            inputStream = url.openStream();
            String jsonData = IOUtils.toString(inputStream);
            XMLSerializer serializer = new XMLSerializer();
            JSON json = JSONSerializer.toJSON(jsonData);
            String xml = serializer.write(json);
            System.out.println(xml);
        }catch(Exception e){
            e.printStackTrace();
        }finally{
     try {
                if (inputStream != null) {
                    inputStream.close();
                }
                url = null;
            } catch (IOException ex) {}
        }
    }
    public static void main(String[] args) {
        new JsonToXMLConverter().getJsonfromXml();
    }
}

Place the sample JSON in the specified path
