Remove the namespace short name and delimiter from start of string.

If the namespace has a verbatim_short_name, that is removed instead of the short_name. The delimiter is only removed if the short_name was found in the identifier.

Parameters:

  • identifier_str (String)
  • namespace (Namespace)

#parse_iso_date(field_name) ⇒ Array<OpenStruct> (private)

Parse an iso date string from the specified column name

The date may be a single date, or an interval of two dates separated by a slash. The second date may omit higher-order elements that are the same as the first date. See en.wikipedia.org/wiki/ISO_8601#Time_intervals for more information.

Parameters:

  • field_name (String)

    The column name to get the date string from

Returns:

  • (Array<OpenStruct>)

    A list of one or two date structs (with year, month, day, hour, minute, second values)

Raises:
