insert \ delete xml sub child node using java

Hi Experts -

I have a sample XML File: say orignal.xml

<?xml version="1.0" encoding="UTF-8"?>
<java version="1.4.2" class="java.beans.XMLDecoder">
 <object class="java.util.Hashtable">
  <void method="put">
   <int>3244</int>
   <object class="com.starwood.valhalla.ecp.security.Property">
    <void property="addrLine1">
     <string>4500 Satellite Blvd</string>
    </void>
    <void property="brand">
     <string>FOUR POINTS</string>
    </void>
    <void property="city">
     <string>Duluth</string>
    </void>
    <void property="country">
     <string>US</string>
    </void>
    <void property="division">
     <string>NORTH AMERICA DIV</string>
    </void>
    <void property="id">
     <int>3244</int>
    </void>
    <void property="name">
     <string>Four Points by Sheraton Atlanta-Duluth</string>
    </void>
    <void property="ownership">
     <string>Franchised</string>
    </void>
    <void property="state">
     <string>GA</string>
    </void>
   </object>
  </void>

<void method="put" >                                     // second child of  <object class="java.util.Hashtable">
..
..
..
</void>
</object>
</java>

Now if I want to insert the second sub-child (which i already have in a StringBuffer i could use the below code suggested by "OBJECTS" earlier -

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
Document original = factory.newDocumentBuilder().parse(new File("original.xml"));
InputSource souce = new InputSource(new StringReader(xmlString))
Document void = factory.newDocumentBuilder().parse(source);
Element object = (Element) original.getElementsByTagName("object").item(0);
Node voidnode = original.importNode(void.getDocumentElement(), true);
object.appendChild(voidnode);

// save to new file

Source source = new DOMSource(original);
Result result = new StreamResult(newfile);
Transformer xformer = TransformerFactory.newInstance().newTransformer();
xformer.transform(source, result);

The above code inserts an new sub-child. Now i'm trying to see if I can also delete a node (sub-child) using the same process.

Any Ideas?


And the way i can identify the node is based on number between the int tag i.e. 3244 or can be any other node number

Please advice

<int>3244</int>
