RegExp pattern to scan for NO HTML tags - need help

I am having to use an existing FormValidator class to check form
elements, and one of the things I must check is to see if someone
entered tags in the string <>; if so, it must flag for that.

However, the catch is that, the way FormValidator class is written, I
can't use this pattern:

/<[^>]+>/

because it needs to check for the pattern of the NEGATION of that for
FormValidator class to work. In other words, it must match the pattern
something like this:

! /<[^>]+>/

But the only way I can do this is to create a pattern and nothing
more; no other code of any kind except the literal pattern formed in
such a way to check for everything BUT a tag!

I also cannot use str_replace and strip out the tags; I can't use
htmlentities and translate the tags.. the requirements are to FLAG the
user if a tag is found but by NOT using the pattern to find one, but
to ONLY use the pattern to find the NEGATION of finding one!!!

Mind bender, I know.

HELP!

Phil
