How to create attributes ?!?

[Christian Geuer-Pollmann <ge...@nue.et-inf.uni-siegen.de>]

I have a problem: I can't create attributes in Xerces: all things other 
than attr are null. Any tip?

Thanks in advance,

Christian

---------------------------------

attr0 (attr0="val0"): prefix(null) localName(null) nsURI(null) attr00 
(attr0="val0"): prefix(null) localName(null) nsURI(null) attr10 
(attr1="val1"): prefix(null) localName(null) nsURI(null)

import org.apache.xerces.dom.DocumentImpl;
import org.w3c.dom.Node;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.NamedNodeMap;
import org.w3c.dom.Attr;

public class attributeGenerator {

   public static void main(String[] args) {

      Document doc = new DocumentImpl();
      Element root = doc.createElement("documentElement");
      doc.appendChild(root);

      // way 1 to generate the attribute
      Attr attr0 = doc.createAttribute("attr0");
      attr0.appendChild(doc.createTextNode("val0"));
      root.setAttributeNode(attr0);

      // way 2 to generate the attribute
      root.setAttribute("attr1", "val1");

      NamedNodeMap nnm = root.getAttributes();

      if (nnm.getLength() != 2) {
         System.err.println("More than two attributes: " + nnm.getLength());
         System.exit(1);
      }

      Attr attr00 = (Attr) nnm.item(0);
      Attr attr10 = (Attr) nnm.item(1);

      printAttr("attr0", attr0 );
      printAttr("attr00", attr00 );
      printAttr("attr10", attr10 );

   }

   public static void printAttr(String description, Attr attr0) {

      String prefix0 = attr0.getPrefix();
      String localName0 = attr0.getLocalName();
      String namespaceURI0 = attr0.getNamespaceURI();

      System.out.println(description + " (" + attr0 + "): prefix(" + prefix0
                         + ") localName(" + localName0 + ") nsURI("
                         + namespaceURI0 + ")");
   }
}
