indentation with modified docs

[Avnish Pundir <ap...@cisco.com>]

Hi,
I am having problem while printing edited XML documents. I have a XML
document which is already indented properly with spaces. Now I am parsing
the document and adding a few new child nodes to it. But when I print the
document, indentation doesn't work out properly.

Here's the code I m using. I have tried all commented code as well.

   DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
   dbf.setNamespaceAware(true);
   //dbf.setValidating(true);
   //dbf.setIgnoringElementContentWhitespace(true);
   DocumentBuilder db = dbf.newDocumentBuilder();
   Document dm = db.parse(new File(configFile));
   Node productsNode = dm.getElementsByTagName("Products").item(0);
   // My own method to find specified node
   Element productNode =
    (Element) XmlUtils
     .getElementsByAttributeName((Element) productsNode, "Product", "name",
"my_product")
     .elementAt(0);
   Element newElement = dm.createElement("Version");
   Text newTextNode = dm.createTextNode(version);
   newElement.appendChild(newTextNode);
   productNode.appendChild(newElement);
   //dm.normalize();
   DOMSource source = new DOMSource(dm);
   DOMResult domResult = new DOMResult();
   Transformer tfm = TransformerFactory.newInstance().newTransformer();
   tfm.setOutputProperty(OutputKeys.INDENT, "yes");
   tfm.setOutputProperty(OutputKeys.METHOD, "xml");
   tfm.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
   tfm.setOutputProperty("{http://xml.apache.org/xslt}indent-amount","2");
   StreamResult result = new StreamResult(System.out);
   tfm.transform(source, result);


I am getting this output
<Inventory_Attributes>
 <Products>
  <Product name="my_product">
   <Version>A</Version>
   <Version>B</Version>
   <Version>C</Version>
  <Version>Newly_added_product</Version>
  </Product>
 </Products>
</Inventory_Attributes>

Whereas the input was
<Inventory_Attributes>
 <Products>
  <Product name="my_product">
   <Version>A</Version>
   <Version>B</Version>
   <Version>C</Version>
  </Product>
 </Products>
</Inventory_Attributes>


(see the wrong indentation of "<Version>Newly_added_product</Version>" tags)

I have tried different count of indent-amount without success. I guess I m
missing something minor over here. Any help would be greatly appreciated.

Thanks
