Creating nodes in a document

[Guru Vasu]

Hi,

I am new to XML and I am trying to create an xml document.

<root>
  <element>
    <name>Name</name>
    <value>Value</value>
  </element>
</root>

In java to form the above document I did the following:

    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    DocumentBuilder builder = factory.newDocumentBuilder();
    Document doc = builder.newDocument();
        Element rootElement = doc.createElement("root");
 

After which I am basically stuck - how would I create a node inside the document (I clearly see this is basic and simple) .... but whichever tutorial I go through wont give me an answer for this (there are parsers to read and convert xmls to DOM back and forth - but how would I form just a simple xml

I am expecting something like

  Node node = new Node("element");//which cant be done since its an interface
  node.addTag("name",Name);
  node.addTag("value", Value);
  root.appendChild(node);

I do not want to use external jars/libs/apis like XStream or castor to do the above.

How would I do the above?

thank you
Guru

<root> <element> <name>Name</name> <value>Value</value> </element></root>

Create a document.Create an element with name root and append to document, continue the same to create the structure and for adding Name , create text node and append to element name.

For creating various xml nodes use Document as factory.(it has all the required methods.)

Thank you Rahul

 
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    DocumentBuilder builder = factory.newDocumentBuilder();
    Document doc = builder.newDocument();
    
    Element rootElement = doc.createElement("root");
    Element subElement = doc.createElement("element");
    Element nameSubElement = doc.createElement("name");
    nameSubElement.appendChild(doc.createTextNode("Name"));
    Element valueSubElement = doc.createElement("value");
    valueSubElement.appendChild(doc.createTextNode("Value"));
    subElement.appendChild(nameSubElement);
    subElement.appendChild(valueSubElement);
    rootElement.appendChild(subElement);
    
    doc.appendChild(rootElement);

The above produced the desired output.

Could you please check and reply if I am doing what you asked me to? and if I can cutshort any of the above calls?

Thank you again Rahul
