rx_anything_but: Match any character(s) except these any (including zero) number of times.
Description
This expression will match everything except whatever characters
the user specifies in the value parameter. It does this by adding a
caret symbol ^ at the beginning of a character set []. Typing
a caret after the opening square bracket negates the character class. The
result is that the character class matches any character that is not in the
character class. Unlike the dot, negated character classes also match
(invisible) line break characters. If you don't want a negated character
class to match line breaks, you need to include the line break characters in
the class.

mode
Matching mode (greedy (default) orlazy). Lazy matching stops after the first match, greedy continues
searching until end of the string and then back-tracks to the last match.
