I want to parse the following url: http://eutils.ncbi.nlm.nih.gov/entrez/eutils/esummary.fcgi?db=nucleotide&id=224589801

As a result I came up with the following met

import java.io.IOException;
import java.net.URL;
import org.apache.xerces.parsers.DOMParser;

import org.w3c.dom.Document;
import org.w3c.dom.NamedNodeMap;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
import org.xml.sax.InputSource;

public class XMLParser {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        parseXml2("http://eutils.ncbi.nlm.nih.gov/entrez/eutils/esummary.fcgi?db=nucleotide&id=224589801");
    }

    public static void parseXml2(String URL) {
        DOMParser parser = new DOMParser();

        try {
            parser.parse(new InputSource(new URL(URL).openStream()));
            Document doc = parser.getDocument();

            NodeList nodeList = doc.getElementsByTagName("Item");
            for (int i = 0; i < nodeList.getLength(); i++) {
                System.out.print("Item "+(i+1));
                Node n = nodeList.item(i);
                NamedNodeMap m = n.getAttributes();
                System.out.print(" Name: "+m.getNamedItem("Name").getTextContent());
                System.out.print(" Type: "+m.getNamedItem("Type").getTextContent());
                Node actualNode = n.getFirstChild();
                if (actualNode != null) {
                    System.out.println(" "+actualNode.getNodeValue());
                } else {
                    System.out.println(" ");                    
                }
            }

        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }
}

Completed the sample code and added a few lines to get the attributes.

This should get you started, although I feel that you need to get yourself up to date with the basic notions of DOM. This site (and many others) can help you with that. Most importantly is understanding the different kinds of nodes there are.
