You cannot do this. It makes no sense. You cannot insert data into the
middle of a file, period, ever. That's not what a file is.
Databases, on the other hand, support this kind of operation just fine. Use
a database. Insert your

Well, you can just ask the user to remember his scores. Or you can
use a database. Or you can write some other sort of file.

You're not appending, you're inserting. You basically will need
to read/write the entire file.

Throw away your requirement (no rewriting of the file) and you have a simple

Simple, yes, but it performs as O(n^2). As your file gets longer and longer,
your application will perform slower and slower. If you don't take care to
do it off the UI thread, you will eventually start getting force-closes
because it stalls out the UI thread.
Not generally recommended.

Another alternative is a journaled approach. Write the updates to a
journal, then merge them with the main file from time to time in a
batch processing step.

Hmm, I'd probably do it one of two ways depending on how big the xml file is
expected to grow.
If it's relatively small, read it into memory, deserialize it, find the
node/tag where you wish to append your node, append it and then re-serialize
it into the same file. But that's only if it's
It would be great if you can give the entire source
code.
Of course, why don't you just send us your Requirements Docs and will
send you back the entire app for you. Free of charge, of course.

Can't be done. (Well, could be done, but would require some file
calisthenics. You'd need to scan through the file to find the closing
tag, figure out what record that begins with -- it might actually span
records -- then write your new tags in place of the closing tag and
restore the closing
Well, there IS one way, sort of.
You can have one XML file that has the outer tags, with a DTD that defines
and entity that references a second file that contains a sequence of XML
forms, and a reference to that entity between the outer tags.
The need for two files is often reason enough to
