Least CPU intensive way to constantly search xml files

Andy B

I need to make a program that stays in the xp/vista system tray. I have to
constantly search xml files to make sure the program stays updated with the
newest xml data. What is the least CPU intensive way to do this? Would it be
Timer or BackgroundWatcher?

Well i guess more info is required to answer this question ,

Where does the XML come from is it a feed ? or is it placed on a shared
network drive or or or ...... :-(

i myself am not such a big fan of timers in background processes , i am more
a thread sleep kind of progger or even bether a event driven
kind of progger ;-) .

The xml would be coming from the computers local drive. The xml would be
updated by some other source and then the program I am working on would need
to keep realtime updates from the xml files.

It seems that if something is changing a local file, then reacting to
filesystemwatcher events would be a resonable approach.

Indeed i would also go for the filesystem watcher as you then can make the
program event driven
thus , change in the file , the filesystem watcher will notify you and then
you reread the file
