consume web service in java

According to the link site, you have to consume this information as an XML file. The following code works, ie it connects and consumes the XML, in this case it printed the information related to santoral and currency, it is just an example.

package com.proyecto.init;

import java.io.BufferedInputStream;
import java.io.IOException;
import java.io.InputStream;

import java.net.URL;
import java.net.URLConnection;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;

import org.w3c.dom.Document;
import org.w3c.dom.NodeList;
import org.xml.sax.SAXException;

public class Main {

    public static void main(String[] args) throws IOException, ParserConfigurationException, SAXException {
        // TODO Auto-generated method stub

        consumir();

    }
    public static void imprimeLista(NodeList lista)
    {
         for (int index=0;index<lista.getLength();index++)
            {
                   System.out.println(lista.item(index).getNodeName()+" "+lista.item(index).getTextContent());

            }

    }

    public static void consumir() throws IOException, ParserConfigurationException, SAXException
    {
        URL url= new URL("http://indicadoresdeldia.cl/webservice/indicadores.xml");
        URLConnection urlConnection = url.openConnection();
        urlConnection.addRequestProperty("User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)");
        InputStream input = new BufferedInputStream(urlConnection.getInputStream());    
        DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
        DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
        Document doc = dBuilder.parse(input);
        NodeList listaSantoral = doc.getElementsByTagName("santoral").item(0).getChildNodes();
        NodeList listaMoneda=doc.getElementsByTagName("moneda").item(0).getChildNodes();
        imprimeLista(listaSantoral);
        imprimeLista(listaMoneda);


    }

}
