Transforming xml doc into string results empty string

Question

Trying to execute Simple parsing from dom.Document to String using javax.xml.transform.Transformer , it results an empty string.

Code :

TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "no");
transformer.setOutputProperty(OutputKeys.METHOD, "xml");
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
DOMSource source = new DOMSource(doc);
StreamResult console = new StreamResult(sw);
transformer.transform(source, console);

Debug Results:

System.out.println(source.getNode().getFirstChild().getNodeName());

                     <root element is displayed>

System.out.println("DONE :"+ console.getWriter().toString());

                      <Empty string is displayed>

Please me know why I get empty string , whereas I need to get the transformed xml string
