It interprets the value as a comma-separated list of tag-like items, where each item is a period-separated list. Subitems(start_index, end_index) – This function breaks apart lists of tag-like hierarchical items such as genres.
If none of the strings match then not_found_value is returned. The string and found_value pairs can be repeated as many times as desired, permitting returning different values depending on string’s value.
If string contains separators then it is also treated as a list and each subvalue is checked. If string is equal to any item (ignoring case) then return the corresponding found_val. Str_in_list(separator, + not_found_val) – interpret the value as a list of items separated by separator then compare string against each value in the list. For example, the title The Dome would not be changed. If the value’s length is less than left chars + right chars + the length of middle text then the value will be returned unchanged.
