Saving a xml file

hi everyone

can please someone help me on this?

i want to know if someone can tell me how do i create a new xml file saving it on my hardisk or how do i add something to an existing xml file and then save it on my harddisk.
the question is how do i do this by using only flash,is it possible?
i don’t wanna use asp or php or cgi or some other server-side scripts

i’ve searched on kirupa forums ans tutorials ans i couldn’t find nothing to do this
thanks

not possible using just Flash.

and if you want to save it to your harddrive, you would have to use something like C++

or you could do it in director
