I am guessing that any server side code to update the XML file will rely
on the server to "lock" files, etc.
Databases are often optimised to allow for multiple "clients" to update,
but most file based commands will lock the file preventing access by
other "clients" so if your code throws a wobbly rather than waiting,
that could be a problem...
Saying that, you could look at using SQLLite for example - this uses a
file based database, but your SQLLite "engine" will handle all of the
access - a lot of PHP installations come with this nowadays and ASP code
also uses ADOBC to connect to Access database files so you will have a
similar system.
The upshot is that using a server side database engine will make life
easier because they will deal with problems like concurrent connections
for you :)

I was considering using an xml file to store high score data for a game. It
is quite possible that this game will have a significant amount of traffic
(certainly in the first few days after launch) and I am now wondering if an
xml file would be suitable. I am not sure what happens in the scenario where
multiple players want to update the highscore at the same time - they will
all need to write to the file. I assume this is the same scenario with a
database but think perhaps updating a database is more efficient.
Anyone care to offer any insight into whether an xml file would be suitable
or not?
Thanks
