Hello,
the problem is, that your regex doesnt seach at beginning or end (for a split a not so
good idea anyway),
but it is a negated character class because of the square brackets and the circumflex
as the first character in it.
It uses any non-word character, apostrophe, '-' or '$' to split the string.
It would be easier to help you, if you tell us what exactly you want to use for split.
