Hi Theo,
To add more nodes (elements) you should use the XML classes provided for
java. In the example I sent you can see the use of the parse method of the
DocumentBuilder class. This method return a class implementing the Document
interface. You can look forward in the java documentation about how to use
this class for the XML elements management.
You should read the XML file and obtain a Document. Then you can manipulate
this document, add or delete nodes, and save it again.
See this URL

I hope this help,
Regards

Hi Alberto,
wow this is very very elegant. Thank you very much. I'll try that. :-)
I still have a question. How to save more data in the XML page?
Do I have to pay attention to some format?
To be more clearly, in my way I used a PrintWriter and a FileOutputStream to
save the data in a simple text file. The format there is very simple: Name"
"Date"\r\t".
Then using a streamtokenizer can retrieve the data. How can I do that with
xml.
(I mean placing the data with some method in the xml)
The names are in top of the tree and the dates in the bottom.
Any suggestion?
Thank you very much again for your time
