Re: Saving dynamically created data on client side?

JS-rookie here... Apologies first, I guess this must have been asked a

somehow drifting into different directions, not providing a
solution... Here's the problem:

You have not searched for "save as", have you?

I have a client-side javascript running, the user creates some data.
At a point the data should be saved to his HDD -- I.e. a "Save as...".
Format of the data, btw, is XML. I couldn't find any pointer on how to
do this client-side only, cross-browser/OS. Any idea how this can be
achieved?

It cannot be done in the desired way with client-side scripting as that
depends on the runtime environment for providing that feature.

If not possible, I'm thinking whether I should submit the data back to
the server into a cgi/php, temporarily storing the file on the server.
I guess the javascript could then pop a new window open, linking to
the server-side script.

It could even be done, and should be made possible too, without client-side
scripting at all.

That one could then serve the file, hopefully
triggering a "Open/Save" dialog box of the browser. But here I'm not
sure how to create, from the JS, a unique ID identifying the correct
handle for the cgi/php. I worry about race-conditions...

I do not see a race condition as your server would generate the file on the
fly, printing it to the standard output, upon request of a specific client
as response message to that client. You can make use of session IDs, though.

I'm currently asking the user to copy&paste the XML data into a new
document and save that. But that's probably the most user-unfriendly
way I could come up with :(

Yes.

Hints or thoughts are highly appreciated!

You are welcome.
