RepeatingGroupMapping

RepeatingGroupMapping

The
RepeatingGroupMapping
Mapper anchor processes a repetitive structure in the input or output.
Use a
RepeatingGroupMapping
when the XML input or output contains a multiple-occurrence data holder. It iterates over occurrences of the data holders. For more information, see Multiple-Occurrence Data Holders.
Under the
RepeatingGroupMapping
, nest Mapper anchors and actions that process each occurrence of the data holder.
The following table describes the properties of the
RepeatingGroupMapping
Mapper anchor:
Property
Description
count
Defines the number of iterations to run. If this property is blank, the iterations continue until the input is exhausted.
current_iteration
Defines a data holder where the
RepeatingGroupMapping
outputs the number of the current iteration.
disabled
Determines whether the Script ignores the component and all of the child components. Use this property to test, debug, and modify a Script. You can choose one of the following options:
  • Selected. The Script ignores the component.
  • Cleared. The Script applies the component.
The default is cleared.
name
A descriptive label for the component. This label appears in the log file and the
Events
view. Use the
name
property to identify the component that caused the event.
notifications
A list of
NotificationHandler
components that handle notifications from nested components. For more information, see Notifications.
on_fail
The action to take if the component fails. You can choose one of the following options:
  • Cleared. Take no action.
  • CustomLog. Write to the user log.
  • LogError. Write an error message to the engine log.
  • LogInfo. Write an information message to the engine log.
  • LogWarning. Write a warning message to the engine log.
  • NotifyFailure. Send a notification.
Default is cleared. For more information about handling component failures, see Failure Handling.
on_iteration_fail
Determines the action when an iteration fails. You can choose one of the following options:
  • Cleared. No action.
  • CustomLog. Writes to the user log.
  • LogError. Writes an error message to the Engine log.
  • LogInfo. Writes an information message to the Engine log.
  • LogWarning. Writes a warning message to the Engine log.
  • NotifyFailure. Triggers a notification.
Use
on_iteration_fail
to write an entry when a single iteration fails. Use the
on_fail
property to write an entry when the entire
RepeatingGroupMapping
fails. For more information, see Failure Handling.
optional
Determines whether a component failure causes the parent component to fail. You can choose one of the following options:
  • Selected. Component failure does not cause the parent component to fail.
  • Cleared. Component failure causes the parent component to fail.
Default is cleared. For more information about component failure, see Failure Handling.
remark
A user-defined comment that describes the purpose or action of the component.
skip_failed_iterations
Determines whether failed iterations are skipped. You can choose one of the following options:
  • Selected.
    RepeatingGroup
    skips over a failed iteration and proceeds with the next iteration. If an iteration succeeds, the
    RepeatingGroup
    succeeds.
  • Cleared.
    RepeatingGroup
    fails if any iteration fails.
The
skip_failed_iterations
property has an effect only if
separator
is defined.
Default is selected.
source
Defines a data holder that contains the source for the mapping. For more information, see Overview of Locators, Keys, and Indexing.
target
Defines a data holder that contains the result of the mapping. For more information, see Overview of Locators, Keys, and Indexing.
