Question

I want to parse the xml file to get the root element. Then append add the tag named first-name under that root tag. How do I do this ? This is what I have been doing right now :

        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        DocumentBuilder db = dbf.newDocumentBuilder();            
        Document document = db.newDocument();

        Element blobKey_E = document.createElement("first-name");
        blobKey_E.appendChild( document.createTextNode( name ) );
        // NOW APPEND blobKey_E to the root element 
        // After getting the root element from the xml in some directory

        TransformerFactory tf = TransformerFactory.newInstance();
        Transformer transformer = tf.newTransformer();
        DOMSource source = new DOMSource(document);
        StreamResult result = new StreamResult(new File("/home/non-admin/NetBeansProjects/Personal Site_Testers/web/xml/xml_1.xml"));
        transformer.transform(source, result);

Answer 1

Element root = document.getDocumentElement();
root.appendChild(document.createElement("first-name"));

Will append first-name to the end of the DOM tree

Inserting into the first position is a little more difficult…

Element root = document.getDocumentElement();
if (root.hasChildNodes()) {
    Node firstChild = root.getFirstChild();
    root.insertBefore(document.createElement("first-name"), firstChild);
} else {
    // Append to as per previous example
}

UPDATE

Eleement firstName = document.createElement("first-name");
firstName.setTextContent("Henry");
