Repeating Group Statements

Repeating Group Statements

A Repeating Group statement is a group statement that can occur multiple times. The input is an XPath expression that can evaluate to a sequence of elements or values.
The Data Processor transformation performs the Repeating Group statement for each element or value that is a result of the Input XPath expression.
When you link between a repeating input schema element and a repeating output schema element, the XMap editor creates a Repeating Group statement in the grid. A element repeats if the
Max. Occurs
value for the element is greater than
1
.

Repeating Group Statement Example

An input schema has the following hierarchy:
Employees Employee (Unbounded) LastName FirstName
When you drag Employee to an output element in the XMap Editor, the Developer tool creates a Repeating Group mapping statement by default. A repeating group might contain mapping statements to return LastName and FirstName for each Employee in the input hierarchical document.
