You are calling getTextContent on a document node. This always results in a null value as you can read in the api docs:

http://download.oracle.com/javase/1.5.0/docs/api/org/w3c/dom/Node.html#getTextContent()

You will get the value if you call dc.getFirstChild().getTextContent() (after appending the element to the document), because now you are calling getTextContent on an element node.
