Reading Xml File using Java Program

Hi All,


Step1: Create a xml file as the xml Standard.

<?xml version="1.0" encoding="UTF-8"?>
<stocks>
       <stock>
              <symbol>Citibank</symbol>
              <price>100</price>
              <quantity>1000</quantity>
       </stock>
       <stock>
              <symbol>Axis bank</symbol>
              <price>90</price>
              <quantity>2000</quantity>
       </stock>
          <stock>
              <symbol>Indian bank</symbol>
              <price>695</price>
              <quantity>1200</quantity>
       </stock>
          <stock>
              <symbol>Canara bank</symbol>
              <price>370</price>
              <quantity>1000</quantity>
       </stock>
          <stock>
              <symbol>Icici    bank</symbol>
              <price>180</price>
              <quantity>3000</quantity>
       </stock>
          <stock>
              <symbol>State bank</symbol>
              <price>990</price>
              <quantity>200</quantity>
       </stock>
</stocks>

Step 2: Save the file as stock.xml (user dependent format).

Java program for read above xml file in console:

import java.io.File;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;

public class xmlRead {

    public static void main(String args[]) {
        try {

            File stocks = new File("C:\\Documents and Settings\\Sify\\Desktop\\stock.xml");
            DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
            DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
            Document doc = dBuilder.parse(stocks);
            doc.getDocumentElement().normalize();

            System.out.println("XML File " + doc.getDocumentElement().getNodeName());
            NodeList nodes = doc.getElementsByTagName("stock");
            System.out.println("==========================");

            for (int i = 0; i < nodes.getLength(); i++) {
            Node node = nodes.item(i);

                if (node.getNodeType() == Node.ELEMENT_NODE) {
                Element element = (Element) node;
                System.out.println("Stock Name: " + getValue("symbol", element));
                System.out.println("Stock Price: " + getValue("price", element));
                System.out.println("Stock Quantity: " + getValue("quantity", element));
                }
            }
        } catch (Exception ex) {
            ex.printStackTrace();
        }
        }

    private static String getValue(String tag, Element element) {
        NodeList nodes = element.getElementsByTagName(tag).item(0).getChildNodes();
        Node node = (Node) nodes.item(0);
        return node.getNodeValue();
    }
}







output:
