This is from a DCT - yes?
Then you want to use a FormAPI callServer() script - which can be written in any language that you chose, and thus you can use whatever code you want to open the file for reading, parse the contents, close the file and open it again for writing, modify the contents, and save the changes.

That code is generally not written in Javascript.

Yes this requirement is form the DCT, on clicking Generate i need to update a xml log file.
can i use the DOM and activeX objects in teamsite (with the javascript)?

I'm confused - your first post says you do not want to use DOM and activeX objects - now you're saying you do want to??

You might be able to do so - however, relying on activeX objects tends to severely limit the portability of your solution (IE on Windows I believe - not sure you can do it with Firefox, and pretty sure you cannot do it on other OS's) - using a callServer script as part of the Generate process (the click on which you can capture and handle) is probably the most "straight forward" way of modifying the DCR just prior to doing the page generation -- though, not knowing your actual requirements, I'd think that the solution would probably best be handled with a callServer script associated within an onItemChange handler long before you get to the Generate option.

Thank You:-)
i have used the callserver() to fulfill the requirement, am new to teamsite, i think i missed giving you some part of the requirement. I have to update the date of generation of the DCR in a log file(which is in XML format) everytime the author generates the DCR (the date is updated against the filename).
