Apache Xerces Parser - Create XML Document

Demo Example

Here is the XML we need to create:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<cars><supercars company="Ferrari">
   <carname type="formula one">Ferrari 101</carname>
   <carname type="sports">Ferrari 202</carname>
</supercars></cars>

Demo Example:
CreateXmlFileDemo.java

package com.tutorialspoint.xml;

import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.transform.Transformer;
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;
import java.io.File;

public class CreateXmlFileDemo {
 
   public static void main(String argv[]) {

      try {
         DocumentBuilderFactory dbFactory =
         DocumentBuilderFactory.newInstance();
         DocumentBuilder dBuilder = 
            dbFactory.newDocumentBuilder();
         Document doc = dBuilder.newDocument();
         // root element
         Element rootElement = doc.createElement("cars");
         doc.appendChild(rootElement);

         //  supercars element
         Element supercar = doc.createElement("supercars");
         rootElement.appendChild(supercar);

         // setting attribute to element
         Attr attr = doc.createAttribute("company");
         attr.setValue("Ferrari");
         supercar.setAttributeNode(attr);

         // carname element
         Element carname = doc.createElement("carname");
         Attr attrType = doc.createAttribute("type");
         attrType.setValue("formula one");
         carname.setAttributeNode(attrType);
         carname.appendChild(
         doc.createTextNode("Ferrari 101"));
         supercar.appendChild(carname);

         Element carname1 = doc.createElement("carname");
         Attr attrType1 = doc.createAttribute("type");
         attrType1.setValue("sports");
         carname1.setAttributeNode(attrType1);
         carname1.appendChild(
         doc.createTextNode("Ferrari 202"));
         supercar.appendChild(carname1);

         // write the content into xml file
         TransformerFactory transformerFactory =
         TransformerFactory.newInstance();
         Transformer transformer =
         transformerFactory.newTransformer();
         DOMSource source = new DOMSource(doc);
         StreamResult result =
         new StreamResult(new File("C:\\cars.xml"));
         transformer.transform(source, result);
         // Output to console for testing
         StreamResult consoleResult =
         new StreamResult(System.out);
         transformer.transform(source, consoleResult);
      } catch (Exception e) {
         e.printStackTrace();
      }
   }
}

This would produce the following result:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<cars><supercars company="Ferrari">
<carname type="formula one">Ferrari 101</carname>
<carname type="sports">Ferrari 202</carname>
</supercars></cars>
