Iteration Functoid Reference

  • Article

 

Use the Iteration functoid ( Icon that represents the Iteration functoid.) to output the number of passes through a repeating structure in an input instance message as that structure is being processed.

Input

Parameter 1: A link from a repeating structure in the source schema.

Output

Output 1: A monotonically increasing number, starting at one (1), for each iteration through the specified repeating structure.

Remarks

For example, if the Iteration functoid is connected to a Record node in the source schema and connected to a Field Element node named "book" in the destination schema, and in a particular instance message the corresponding input element occurs three times, the following output is produced:

<book>1</book>  
<book>2</book>  
<book>3</book>
