AttributeSplitter

Splits attribute values into parts, based on a delimiter or fixed-width pattern, and creates a list attribute containing one list element for each part.

Jump to Configuration

Typical Uses

  • Converting a delimited list of values into an FME list attribute
  • Extracting one part of an attribute value based on column-aligned text with a known structure

How does it work?

Once connected to an input feature stream, the AttributeSplitter lets you select an Attribute to Split. The value for that attribute is divided into parts based on parameter selections, and the results added to a new list attribute.

Splitting can be done with either a delimiter (such a comma-separated list of values), or by providing a format string that identifies the width of each part in a piece of column-aligned text.

In the case of a delimited list, the number of parts in the value can be variable. A field qualifying character may also be specified for cases where the delimiter appears within the string as a non-delimiting value (such as commas within addresses in comma-separated strings).

For fixed-width splitting, parts will be extracted exactly according to the format string provided.

Whitespace may be trimmed from the resulting values, and Empty Parts - parts with no resulting value - may be kept or dropped.

The new list attributes can be used with other list-based transformers. Alternatively, you can expose specific list elements to be used as individual attributes (see example below).

Examples

Usage Notes

  • Lists are usually indicated in FME Workbench by name, followed by a pair of curly brackets - mylist{}.
    A specific list element contains its number between the brackets - mylist{0}
  • To access specific list elements in FME Workbench, right-click on a list name in the attribute list and choose Expose Elements.
  • For information on working with lists, see List Attributes.
  • To split attributes using regular expression pattern matching, consider using the StringSearcher.
