How can I negate a whole string by regular expression?

Hello developers,

does anyone know how can I exclude (negate) a whole string by a regular expression?

Until so far, I tried to use following: Regexp regex_negate = regexp2("^(?!.*string_to_be_negated).*$"),

but this does not work. It seems that DXL does not support the negative lookahead.
