For Each

ActionStep Reference » Programming » Flow Control » For Each 

The For Each ActionStep allows you to iterate and process all elements of a parameter list individually. For Each has an inner node in which you can embed the ActionSteps that are repeatedly executed in the loop.

The ActionStep has the following input parameters:

name	Description
List Reference	The reference to a specified list to be iterated. Allowed Context Scopes [Local reference]

Results:

The ActionStep returns the following results:

name	description
Data	The root node of the data after the iteration.
Row	Contains the current index of the executed loop. Allowed Context Scope [Fixed, Local, Global] Allowed Context Types [Variable, Parameter, Result]

The sub-elements of Row are created dynamically and contain the currently read data after each loop cycle.

Example 1 (Loops through the items in a list):

This example reiterates and displays the items of a local list named Consumer Product. The Result is then output via Message Box.

Example 2 (Display the name and size of a file in a folder):

This example iterates the contents of a local folder named music. The value of the File is truncated and the iterated data is then output via Message Box.
