[thelist] ColdFusion and checking HTML

[Joshua Olson]

Hmmm... interesting problem.  Unfortunately, the algorithm you mentioned
will not be enough to solve the problem, though it will get close.  If you
are happy with close, then yes, the loop can be constructed.  It'll be slow
as h**l in ColdFusion, but it can be done.

Try converting the string to an array using > is the delimiter.  Then loop
through the array checking the items against your checklist.
