I have an XML document that has an embedded DTD.  I have a method that will update the value of an element passed and save the doc. When the doc is saved the element is updated as expected, however the embedded DTD is wiped out.  How do I preserve the DTD?

Node resultNode = findSubNode(elementName, mDoc.getDocumentElement());
            if (resultNode != null) {
                  resultNode.setTextContent(value);
                  Transformer xformer;
                  try {
                        xformer = TransformerFactory.newInstance().newTransformer();
                        xformer.transform(new DOMSource(mDoc), new StreamResult(new File(mXmlPath)));
                  } catch (Exception e) {
                        XmlError = e.getMessage();
                        return false;
                  }
                  return true;
            } else
                  return false;
      }

You can set to the transformer doctype properties from document.
DocumentType docType = mDoc.getDoctype();
if (docType.getPublicId() != null) {
    xformer.setOutputProperty(OutputKeys.DOCTYPE_PUBLIC, docType.getPublicId());
}
if (docType.getSystemId() != null) {
    xformer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM, docType.getSystemId());
}
