Create - XML File (Document)
In this section, you will learn to create a XML
document using the DOM APIs. This XML document uses 1.0 version
and UTF-8 encoding.
Description of program:
This program helps in creating a XML document on
the console. This program asks for the number of elements to be added in the
generated xml file. It takes the root name at the console and passes it in
the createElement() method. It creates the Element object and
invokes the Document object . Depending upon the given number, it
creates that much elements and fills them with data,. Finally, it displays the
generated XML file with its version and encoding.
Here is Java File: CreatXMLFile.java
import java.io.*;
import javax.xml.parsers.*;
import javax.xml.transform.*;
import javax.xml.transform.dom.*;
import javax.xml.transform.stream.*;
import org.w3c.dom.*;
public class CreatXMLFile {
public static void main(String[] args) throws Exception {
BufferedReader bf = new BufferedReader(new InputStreamReader(System.in));
System.out.print("Enter number to add elements in your XML file: ");
String str = bf.readLine();
int no = Integer.parseInt(str);
System.out.print("Enter root: ");
String root = bf.readLine();
DocumentBuilderFactory documentBuilderFactory =
DocumentBuilderFactory.newInstance();
DocumentBuilder documentBuilder =
documentBuilderFactory.newDocumentBuilder();
Document document = documentBuilder.newDocument();
Element rootElement = document.createElement(root);
document.appendChild(rootElement);
for (int i = 1; i <= no; i++){
System.out.print("Enter the element: ");
String element = bf.readLine();
System.out.print("Enter the data: ");
String data = bf.readLine();
Element em = document.createElement(element);
em.appendChild(document.createTextNode(data));
rootElement.appendChild(em);
}
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
DOMSource source = new DOMSource(document);
StreamResult result = new StreamResult(System.out);
transformer.transform(source, result);
}
}
