How to search for a string which is not preceded by another string?

    I wish to search, using regular expressions, for a string (say •water) where this is not preceded by "<W ", that is "<W" followed by a space.

    E.g. "<W •water" or "<W •Content" must not match. I only need the occurrences where the "<W " does not precede the string. The • will always precede the word.

    How can I achieve this? I am using UltraEdit version 18.10.0.1018.

      A Perl regular expression search with (?<!<W )•water searches for •water and uses a negative lookbehind to verify if there is not "<W " preceding found •water for a positive match.
