Re: replace an instance uploading an xml file

Federico,

I'm not sure of understanding your approach, but it seems that changes the
@src of the instance data by the location of the input data introduced by
the user. Then, the instance data is reloaded from the new source?

Even so, I will have problems if I want that the instance data will contain
more data than the user can introduce with their xml file. I could divide
the instance data in more instances data, and replacing one of them with
those of the user input, but I suppose that then I would have problems to
submitting all of them.

Leigh,

You might think that doing this in JavaScript would be easier and keep the
action all on the client, but most user agents prevent scripted access to
local file data.

But if the file is loaded, is not supposed that user wants to send to the
web? Loading a file can't be interpreted like giving permission... or not?

Thanks to both. I will be doing the cgi, it seems to be the best option for
me.
