Value splitters

Value splitters are objects similar to lists, which can contain a structure data type, which consists of a sequence of field values. Structures can be regarded also as an ordered sequence of field values. A Value Splitter is bound to a target node. By repeatedly calling the function next the function returns the next field value from the structure until all values are processed. So the field values from the structure value are distributed into the fields, which are located directly within the bound node. The name of a value splitter is the name of the node to which it is bound. Since structure data can be represented as a csv file line or a fixed record file line, there are two operation types of a value splitter, csv or fix. Only a single function with many different methods is used with value splitters: value-splitter(). Some advanced methods of this function also allow general operations on data collections, as well as the order, elimination of duplicates, and the selection of values from a collection of values.
