    Hi!

    I would use Generate Attributes with a formula like replaceAll( attribute, ".+PERIODICITY=(.+)\\|DIRECTION.+", "$1") .

    The regular expression searches for the appropriate string. If the format varies (e. g. DIRECTION is not always on the same place), you need to change the regular expression.
