Having problem in modifying the value of node in xml

[Rajesh k Jha]

Hello to everyone,
Actually i am using XML as database to store value temporarily and later on it will be uploaded on the server and will be updated in the database, but currently i am having following problem.

1. I can save my data in the XML format in the local disk, but when i am editing some part node value, how can i override this value in the xml file.

I am attaching the source code of xml file.

If i made some changes in the VIF2 using edit form developed in SWING then how can i update it in the XML file.

Can someone please guide me on this, as this is very urgent and i am not getting any clue for this on Google.

I can save my data in the XML format in the local disk,

Exactly how are you doing that? Are you building a Document in memory or just writing text?

I recommend Harold's free online book for examples of this sort of thing.

The "edit" process should (1) read the file and (2) create a "new" file with the modification. Basically, the new file replaces the old file.

Hello William and Jimmy,

Thanks so much for your attention, I got my problem solved, as I was able to replace the node in memory but not in file, In google i got one help that i want to share with all

  
firstVIFBlockCodeNode.item(0).setNodeValue(blockValue);
  

and then at last when all setting of node is done in memory
use below code to write it in the file

 
         TransformerFactory transformerFactory = TransformerFactory.newInstance();
         Transformer transformer = transformerFactory.newTransformer();
         DOMSource source = new DOMSource(doc);
         StreamResult result =  new StreamResult(new File("D:/FileAISES/SavingVIF.xml"));
         transformer.transform(source, result);

This will help someone as a solution to someone else...
Thanks again...

This is how we can set the value of
