[Sheflug] quick Reg exp exercise

["Chris Johnson" <chris [at] xxxxxxxxxxxxx>]

I've downloaded a script to base a web site on but I want my version of it
to be W3C compliant and there are all sorts of errors.

The first one is that all html tags should be lowercase, at least that's
what I think the W3C error is getting at.  Is there a reg exp that will
search through all my files and exchange <XX> for <xx> and </XX> for </xx>
without messing up variable names (is PHP case sensitive) (eg <XX
color=$MyColour> I know colour should be set in css files but I couldn't
think of another example)

I could do <XX> for <xx> but not doing the $XxXxx as well will be testing.

Thanks

ChrisJ
