How to create XML file in Java – (JDOM Parser)

In this example, we show you how to use JDOM parser to create document, element and attribute in a XML file.

1. XML File

At the end of this example, following XML file will be created.

File : file.xml

<?xml version="1.0" encoding="UTF-8"?>
<company>
  <staff id="1">
    <firstname>yong</firstname>
    <lastname>mook kim</lastname>
    <nickname>mkyong</nickname>
    <salary>199999</salary>
  </staff>
  <staff id="2">
    <firstname>low</firstname>
    <lastname>yin fong</lastname>
    <nickname>fong fong</nickname>
    <salary>188888</salary>
  </staff>
</company>

3. JDOM Example

JDOM example to create above XML file.

import java.io.FileWriter;
import java.io.IOException;
import org.jdom.Attribute;
import org.jdom.Document;
import org.jdom.Element;
import org.jdom.output.Format;
import org.jdom.output.XMLOutputter;

public class WriteXMLFile {
	public static void main(String[] args) {

	  try {

		Element company = new Element("company");
		Document doc = new Document(company);
		doc.setRootElement(company);

		Element staff = new Element("staff");
		staff.setAttribute(new Attribute("id", "1"));
		staff.addContent(new Element("firstname").setText("yong"));
		staff.addContent(new Element("lastname").setText("mook kim"));
		staff.addContent(new Element("nickname").setText("mkyong"));
		staff.addContent(new Element("salary").setText("199999"));

		doc.getRootElement().addContent(staff);

		Element staff2 = new Element("staff");
		staff2.setAttribute(new Attribute("id", "2"));
		staff2.addContent(new Element("firstname").setText("low"));
		staff2.addContent(new Element("lastname").setText("yin fong"));
		staff2.addContent(new Element("nickname").setText("fong fong"));
		staff2.addContent(new Element("salary").setText("188888"));

		doc.getRootElement().addContent(staff2);

		// new XMLOutputter().output(doc, System.out);
		XMLOutputter xmlOutput = new XMLOutputter();

		// display nice nice
		xmlOutput.setFormat(Format.getPrettyFormat());
		xmlOutput.output(doc, new FileWriter("c:\\file.xml"));

		System.out.println("File Saved!");
	  } catch (IOException io) {
		System.out.println(io.getMessage());
	  }
	}
}
