I've been reading O'Reilly's "Mastering Regular Expressions" (haven't quite
finished) and to my understanding using [^] is only for single characters.
Using ^ outside a character class (meaning the [] format) means "match the
start of a line." If you can be reasonably certain, by having a familiarity
with your data, that your inside sting will not include a "<", you will be
able to use:
REFind("<!-- snip -->[^<]<!-- /snip -->", file)
but again, if there are any <'s between those snips you'll have to find
another way. Maybe when I finish the book I'll know a good way to figure
this sort of thing out.

Try this (untested, but should be darn close):
REFind("<!-- snip -->^(<!-- /snip -->)<!-- /snip -->", file)
In the first one you tried, must realize that regexp are by default
"hungry". They will match on the largest match possible. In your case this
meant that the regexp was matching the first opening tag all the way to the
last closing tage due to the ".*".
In your second one you were much closer but "[^<!-- /snip -->]" means to
match any of the following: not "<" or ! or - or / or s or n, etc.
Try it with parens as above to say "not this pattern".

Subject: Regular Expressions
I'm having trouble and I was hoping someone can help me.
Senario: I have a page that I'm trying to extract pieces from. To mark the
section I'm trying to edit, I've place <!-- snip --> and <!-- /snip -->
around the section. Next, I'm opening the file (CFFILE) and doing a regular
expression to find that section: REFindNoCase("<!-- snip
-->.*<!-- /snip -->", file). Works great. Now, to make several places on
the page editable, I placed several snips. Now the regular expression
only finds the first open snip and the last close snip, including all the
others inside.
Question: How do I find just those sections? I thought about doing
REFindNoCase("<!-- snip -->[^<!-- /snip -->]*", file), but that doesn't
work - it excludes all the characters instead of the whole string. Is there
a way to exclude a complete string instead of just a group of
characters?
Any suggestions would be most helpful. Any example would be great too.
