XSS Global clean

[eluser]Mat-Moo[/eluser]
I have this enabled as a matter of security (But still do some checking as well), but I have a new special controller I am writing that picks up an rss feed as a post which I need NOT to be sanitised. From what I've read on here I have to disable global CSS then add it to all my inputs (grrr) - or is there another way? [even print_r($_POST) is sanitised].

Any other input on this is welcome !
