Description

I am working with xalan-2.3.1.jar file. I tried following code to generate the
output.
try {
DocumentBuilderFactory dbf =
DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
//dbf.setValidating(true);
//dbf.setIgnoringElementContentWhitespace(true);
DocumentBuilder db = dbf.newDocumentBuilder();
Document dm = db.parse(new File("myinput.xml"));
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
("new_added_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);
} catch (Exception e) {}

Here's my output
<?xml version="1.0" encoding="UTF-8"?>
<Inventory_Attributes>
<Products>
<Product name="my_product">
<Version>A</Version>
<Version>B</Version>
<Version>C</Version>
<Version>new_added_version</Version>
</Product>
</Products>
</Inventory_Attributes>

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

See the new Element "<Version>new_added_version</Version>" is not indented at
all. However if I substitue the "productNode.appendChild(newElement);" with
"productNode.insertBefore(newElement,productNode.getLastChild());"
Indentation work out as expected. Here's the output with modified code

<?xml version="1.0" encoding="UTF-8"?>
<Inventory_Attributes>
<Products>
<Product name="my_product">
<Version>A</Version>
<Version>B</Version>
<Version>C</Version>
<Version>new_added_version</Version>
</Product>
</Products>
</Inventory_Attributes>

But problem over here is that new node is added AT THE END (it should be just
before last element "<Version>C</Version>" in above case).
