List Data Types

List Data Types

A data holder can be a space-separated list. The Script filters the text retrieved by the
Content
anchor to match the types of the list items.
Suppose that the schema defines an attribute called
grades
, which is a list of
xs:integer
items. In teh above example, if you map the
Content
anchor to
grades
, the anchor returns a list of the integers in the string:
81 56 95
If the
grades
attribute belongs to an element called
Students
, the XML output is:
<Students grades=”81 56 95" />
If you define the
Content
anchor with
direction = backward
, the list is reversed:
<Students grades=”95 56 81" />
