Inserting a node in an existing xml document

[indu mathikrr]

Hi!

i need to insert a new element in an existing xml document.This is my sample xml document..

   <?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE folks SYSTEM "sample.dtd">
<folks>
<person>
<name>sophie</name>
<phone>999555-8888</phone>
<email>[e-mail]</email>
</person>
<person>
<name>saran</name>
<phone>213545697</phone>
<email>[e-mail]</email>
</person>
<person>
<name>priya</name>
<phone>33333</phone>
<email>[e-mail]</email>
</person>
</folks> 

I'll get get the node name that has to be and its value and the position to add the node all in run time only.
I'm displaying the xml in a form display in a jsp page and i have a check box for every node. So when i click a node i'll display the elements that can be added under that corresponding node using the DTD of that xml.
Hereby i'm getting the node name its textvalue and Xpath..
I couln't get the xpath correctly and so i couln't add that element in the proper node.
Here is my code....
It adds the node name and node value but not in the correct location...It adds under the first <person> even if i select second <person>

   
      try
      {
      DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory.newInstance();  
      Document document = documentBuilderFactory.newDocumentBuilder().parse(fname);
      XPath xpath = XPathFactory.newInstance().newXPath();       

      //getting the node name where child node has to be added and adding the node      

      Node node = (Node) xpath.evaluate(nodepath, document, XPathConstants.NODE);
      Node childnode=document.createElement(nodename);  
      node.appendChild(childnode); 
      childnode.setTextContent(nodevalue);

      Source source = new DOMSource(document);
      File file = new File(fname);  
      Result result = new StreamResult("books.xml");
      Transformer transformer = TransformerFactory.newInstance().newTransformer();
      transformer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM, "books.dtd");
      transformer.transform(source, result);
      out.close();
      }   

i'm going wrong in the nodepath as i'm retrieving the nodepath as "/folks/person/name".. it cant identify the exact <person> and so it considers the first <person>

Can you give me any idea to solve this issue?

Thanks in advance,
Indu
