How to add namespaces before a tag name in XML??

Question

Dear friends:
I have following code, and hope to add namespaces before the tagname such as Company, Location and even any attributes in this xml,
Can you help throw some lights??
Thanks in advance.
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import org.w3c.dom.Attr;
import org.w3c.dom.Document;
import com.sun.org.apache.xml.internal.serialize.OutputFormat;
import com.sun.org.apache.xml.internal.serialize.XMLSerializer;
import org.w3c.dom.Element;
public class DocWriteDOMStart {
    public static void main(String[] av) throws IOException {
        DocWriteDOMStart dw = new DocWriteDOMStart();
        Document doc = dw.makeDoc();
        ((org.apache.crimson.tree.XmlDocument)doc).write(System.out);
    /** Generate the XML document */
    protected Document makeDoc() {
        try {
            DocumentBuilderFactory fact = DocumentBuilderFactory.newInstance();
            DocumentBuilder parser = fact.newDocumentBuilder();
            Document doc = parser.newDocument();
            Element root = doc.createElement("Company");;
            doc.appendChild(root);
            Element loc = doc.createElement("Location");
            root.appendChild(loc);
            Element emp = doc.createElement("Employee");
            loc.appendChild(emp);
            emp.appendChild(doc.createTextNode("Daniel Bush"));
            Element emp2 = doc.createElement("Employee");
            loc.appendChild(emp2);
            emp2.appendChild(doc.createTextNode("Sandy Moore"));  
            Element dept = doc.createElement("Department");
            Element e = (Element)dept;
            e.setAttribute("Nationality", "USA");
            e.setAttributeNS("www.yahoo.com", "dept", "http://www.google.com");
            //e.setAttributeNodeNS(newAttr);
            loc.appendChild(e);
            e.appendChild(doc.createTextNode("IT Depart"));
            return doc;
        } catch (Exception ex) {
            System.err.println(ex.getClass());
            System.err.println(ex.getMessage());
            return null;
}and I got
<?xml version="1.0" encoding="UTF-8"?>
<Company>
  <Location>
    <Employee>Daniel Bush</Employee>
    <Employee>Sandy Moore</Employee>
    <Department Nationality="USA" dept="http://www.google.com">IT Depart</Department>
  </Location>
</Company>hope to add namespaces before the tagname such as Company, Location and even any attributes such as dept, nationality etc in this xml,
I try but fail.

You would have to write code that does that, then. Right now your code writes that part of your XML as elements that aren't in a namespace. I can tell you know there are different methods to write elements that are in a namespace because you used a different method to try to write an attribute that is in a namespace.
