XML Get Next Node

This XML tool returns the node at the current iterator position and returns an iterator pointing to the next position in the list. As the iterator is just a variable, you can make copies at any time to save a certain position. By using the same variable as input and output iterator, you can easily iterate over the list by connecting the Success path back to this tool (after processing the node, of course).
The tool takes the ‘End’ exit when the iterator points to an empty list or the iteration is complete (list traversed to end).

Inputs

Node Iterator

Current position in the node list.

Outputs

Node Iterator Next

Iterator pointing to the next position in the list.

Node

Node at the current position. NULL if list is empty.

Exit Paths

Success

Successfully retrieved node at the current position.

End

Iteration complete.

Note: This path is taken if this tool is invoked again after the last item has been retrieved. The ‘Node’ output variable is set to a NULL node.

Failure

This path is taken if the operation fails.
