Hmm..i tried what you have and it worked for me. Here is what i tried
package com.scratch;
import java.io.StringReader;
import java.io.StringWriter;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.xml.sax.InputSource;
public class Scratch {
     private static String xmlString = "<?xml version=\"1.0\" encoding=\"UTF-8\" standalone='yes'?><ABCs xmlns=\"http://xmlns.oracle.com\"></ABCs>";
     private static Document doc = null;
      * @param args
     public static void main(String[] args) {
          try {
               loadXMLFromString(xmlString);
          } catch (Exception e) {
               // TODO Auto-generated catch block
               e.printStackTrace();
          modifyXML();
          String newXML = getStringFromDocument(doc);
          System.err.println(newXML);
      public  static void loadXMLFromString(String xml) throws Exception
             DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
             DocumentBuilder builder = factory.newDocumentBuilder();
             InputSource is = new InputSource(new StringReader(xml));
             doc =  builder.parse(is);
      public static void modifyXML()
           Node myNode = doc.getElementsByTagName("ABCs").item(0);                       
         Element anElem = doc.createElement("ABC");           
         myNode.appendChild(anElem);
      public static String getStringFromDocument(Document doc)
          try
             DOMSource domSource = new DOMSource(doc);
             StringWriter writer = new StringWriter();
             StreamResult result = new StreamResult(writer);
             TransformerFactory tf = TransformerFactory.newInstance();
             Transformer transformer = tf.newTransformer();
             transformer.transform(domSource, result);
             return writer.toString();
          catch(TransformerException ex)
             ex.printStackTrace();
             return null;
}and i got this xml back
<?xml version="1.0" encoding="UTF-8"?><ABCs xmlns="http://xmlns.oracle.com"><ABC/></ABCs>and i am using java se 1.6
