Get Tag name from XML with Java

nodeName() bør returnere tag navnet for elementer !

Eksempel:

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.ArrayList;

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.FactoryConfigurationError;
import javax.xml.parsers.ParserConfigurationException;

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

public class DomTest5 {
  private final static String XML_FILE = "C:\\domtest.xml";
  public static void main(String[] args) {
      writeXml(XML_FILE);
      readXml(XML_FILE);
  }
  private static void writeXml(String filename) {
      try {
        PrintWriter pw = new PrintWriter(new FileOutputStream(filename));
        pw.println("<?xml version='1.0' standalone='yes'?>");
        pw.println("<list>");
        pw.println("<a>1</a>");
        pw.println("<bb>2</bb>");
        pw.println("<ccc>3</ccc>");
        pw.println("</list>");
        pw.close();
      } catch (FileNotFoundException e) {
        e.printStackTrace();
      }
  }
  private static void readXml(String filename) {
      try {
        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        DocumentBuilder db = dbf.newDocumentBuilder();
        Document doc = db.parse(new File(filename));
        NodeList list = doc.getDocumentElement().getChildNodes();
        for(int i = 0; i < list.getLength(); i++) {
            if(list.item(i).getNodeType()==Node.ELEMENT_NODE) {
                System.out.println(list.item(i).getNodeName());
            }
        }
      } catch (FactoryConfigurationError e) {
        e.printStackTrace();
      } catch (ParserConfigurationException e) {
        e.printStackTrace();
      } catch (SAXException e) {
        e.printStackTrace();
      } catch (IOException e) {
        e.printStackTrace();
      }
      return;
  }
}

output:

a
bb
ccc

Ctrl-C, Ctrl-V
