parsing XML with DOMParser

[Yang Xiao]

Hi all,
I'm having some problems with parsing XML with DOMParser.
What I want is to filter out particular elements in the XML, the
sample XML looks like this.

Thanks in advance.

and my code(which doesn't work J)
import java.io.IOException;
import org.apache.xerces.parsers.DOMParser;
import org.w3c.dom.Document;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
import org.xml.sax.SAXException;
// A Simple DOM Application
public class BasicDOM2 {

// Constructor
public BasicDOM2(String xmlFile) {

// Create a Xerces DOM Parser
DOMParser parser = new DOMParser();

// Parse the Document
// and traverse the DOM
try {
parser.parse(xmlFile);
Document document = parser.getDocument();
traverse(document);
} catch (SAXException e) {
System.err.println(e);
} catch (IOException e) {
System.err.println(e);
}
}

// Traverse DOM Tree. Print out Element Names
private void traverse(Node node) {

int type = node.getNodeType();
if (type == Node.ELEMENT_NODE &&
node.getNodeName().equals("ARTIST")){
System.out.print(node.getNodeName() + ": ");
System.out.print(node.getNodeValue());
} else {
}

/*
if (type == Node.TEXT_NODE){// &&
node.getNodeName().equals("ARTIST"))
System.out.println(node.getNodeValue());
// System.out.println(node.getLocalName());
}else{
}
*/

NodeList children = node.getChildNodes();
if (children != null) {
for (int i=0; i< children.getLength(); i++)
traverse(children.item(i));
}

}

// Main Method
public static void main(String[] args) {
BasicDOM2 basicDOM = new BasicDOM2("c:/temp/cd2.xml");
}
}
