How to create XML file with specific structure in Java [duplicate]

Question

I would like to create XML file using Java.

My XML file structure:

<?xml version="1.0" encoding="UTF-8"?>
<CONFIGURATION>
    <BROWSER>chrome</BROWSER>
    <BASE>http:fut</BASE>
    <ENVIRONMENT>abcd</ENVIRONMENT>
    <USER>john</USER>
    <PASSWORD>abcd123</PASSWORD>
    <ORGANIZATION>Tim</ORGANIZATION>
    <EMPLOYEE>
        <EMP_NAME>Anhorn, Irene</EMP_NAME>
        <ACT_DATE>20131201</ACT_DATE>
        <DATE_IN>20131201</DATE_IN>
        <CLOCK_IN>0800</CLOCK_IN>
        <DATE_OUT>20131201</DATE_OUT>
        <CLOCK_OUT>1600</CLOCK_OUT> 
    </EMPLOYEE>
    <EMPLOYEE>
        <EMP_NAME>Arlegui, Karen Jay</EMP_NAME>
        <ACT_DATE>20131201</ACT_DATE>
        <DATE_IN>20131201</DATE_IN>
        <CLOCK_IN>1600</CLOCK_IN>
        <DATE_OUT>20131202</DATE_OUT>
        <CLOCK_OUT>0000</CLOCK_OUT> 
    </EMPLOYEE>
</CONFIGURATION>

Answer 1

You can use the JDOM library in Java. Define your tags as Element objects, document your elements with Document Class, and build your xml file with SAXBuilder. Try this example:

//Root Element Element root=new Element("CONFIGURATION"); Document doc=new Document(); //Element 1 Element child1=new Element("BROWSER"); //Element 1 Content child1.addContent("chrome"); //Element 2 Element child2=new Element("BASE"); //Element 2 Content child2.addContent("http:fut"); //Element 3 Element child3=new Element("EMPLOYEE"); //Element 3 --> In this case this element has another element with Content child3.addContent(new Element("EMP_NAME").addContent("Anhorn, Irene"));  //Add it in the root Element root.addContent(child1); root.addContent(child2); root.addContent(child3); //Define root element like root doc.setRootElement(root); //Create the XML XMLOutputter outter=new XMLOutputter(); outter.setFormat(Format.getPrettyFormat()); outter.output(doc, new FileWriter(new File("myxml.xml")));

public static void main(String[] args) {  try {      DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();     DocumentBuilder docBuilder = docFactory.newDocumentBuilder();     Document doc = docBuilder.newDocument();     Element rootElement = doc.createElement("CONFIGURATION");     doc.appendChild(rootElement);     Element browser = doc.createElement("BROWSER");     browser.appendChild(doc.createTextNode("chrome"));     rootElement.appendChild(browser);     Element base = doc.createElement("BASE");     base.appendChild(doc.createTextNode("http:fut"));     rootElement.appendChild(base);     Element employee = doc.createElement("EMPLOYEE");     rootElement.appendChild(employee);     Element empName = doc.createElement("EMP_NAME");     empName.appendChild(doc.createTextNode("Anhorn, Irene"));     employee.appendChild(empName);     Element actDate = doc.createElement("ACT_DATE");     actDate.appendChild(doc.createTextNode("20131201"));     employee.appendChild(actDate);     TransformerFactory transformerFactory = TransformerFactory.newInstance();     Transformer transformer = transformerFactory.newTransformer();     DOMSource source = new DOMSource(doc);     StreamResult result = new StreamResult(new File("/Users/myXml/ScoreDetail.xml"));     transformer.transform(source, result);     System.out.println("File saved!");   } catch (ParserConfigurationException pce) {     pce.printStackTrace();   } catch (TransformerException tfe) {     tfe.printStackTrace();}} 

The values in you XML is Hard coded.

Use JAXB: http://www.mkyong.com/java/jaxb-hello-world-example/

package com.mkyong.core;

import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement
public class Customer {

    String name;
    int age;
    int id;

    public String getName() {
        return name;
    }

    @XmlElement
    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    @XmlElement
    public void setAge(int age) {
        this.age = age;
    }

    public int getId() {
        return id;
    }

    @XmlAttribute
    public void setId(int id) {
        this.id = id;
    }

}

package com.mkyong.core;

import java.io.File;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Marshaller;

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

      Customer customer = new Customer();
      customer.setId(100);
      customer.setName("mkyong");
      customer.setAge(29);

      try {

        File file = new File("C:\\file.xml");
        JAXBContext jaxbContext = JAXBContext.newInstance(Customer.class);
        Marshaller jaxbMarshaller = jaxbContext.createMarshaller();

        // output pretty printed
        jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);

        jaxbMarshaller.marshal(customer, file);
        jaxbMarshaller.marshal(customer, System.out);

      } catch (JAXBException e) {
        e.printStackTrace();
      }

    }
}

There is no need for any External libraries, the JRE System libraries provide all you need.

I am infering that you have a org.w3c.dom.Document object you would like to write to a file

To do that, you use a javax.xml.transform.Transformer:

import org.w3c.dom.Document
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerConfigurationException;
import javax.xml.transform.dom.DOMSource; 
import javax.xml.transform.stream.StreamResult; 

public class XMLWriter {
    public static void writeDocumentToFile(Document document, File file) {

        // Make a transformer factory to create the Transformer
        TransformerFactory tFactory = TransformerFactory.newInstance();

        // Make the Transformer
        Transformer transformer = tFactory.newTransformer();

        // Mark the document as a DOM (XML) source
        DOMSource source = new DOMSource(document);

        // Say where we want the XML to go
        StreamResult result = new StreamResult(file);

        // Write the XML to file
        transformer.transform(source, result);
    }
}
