XML parsers in JAVA

Question

Hi all,
I need to parse XML files in JAVA. Is there any specific package in java for XML parsing?

Answer 1

Example for using DOM :
import java.io.File;
import javax.xml.parsers.*;
import org.w3c.dom.*;
// using DOM
public class ParseXML_Dom {
    public static void main(String[] args) {
        File file = new File("test.xml");
        try {
            DocumentBuilder builder =
                    DocumentBuilderFactory.newInstance().newDocumentBuilder();
            Document doc = builder.parse(file);
            NodeList nodes = doc.getElementsByTagName("topic");
            for (int i = 0; i < nodes.getLength(); i++) {
                Element element = (Element) nodes.item(i);
                NodeList title = element.getElementsByTagName("title");
                Element line = (Element) title.item(0);
                System.out.println("Title: " + getCharacterDataFromElement(line));
                NodeList url = element.getElementsByTagName("url");
                line = (Element) url.item(0);
                System.out.println("Url: " + getCharacterDataFromElement(line));
        } catch (Exception e) {
            e.printStackTrace();
     The file "text.xml" might contain this :
<?xml version="1.0"?>

    public static String getCharacterDataFromElement(Element e) {
        Node child = e.getFirstChild();
        if (child instanceof CharacterData) {
            CharacterData cd = (CharacterData) child;
            return cd.getData();
