This section explains how to use a group node to parse multiple elements in an array inside a Cargo workflow |
You find yourself in the following situation:
- You used a node (e.g. a People Data Labs search) that produces an array with multiple elements inside
- You need to perform an operation on each of these elements programmatically (as you would inside a function when coding)
This is where you should use the group node. The alternative would be to treat every element in the array one-by-one.\
How to use it:
- Insert a Group node after the node producing the array (PDL - Search in the example below)
- Within the expression, define where the array is found ({{nodes.node_1}} in the example below)
- Click on the expand window section at the bottom of the group node, which will open a sub-workflow window
- The sub-workflow works exactly as a normal worfklow, except that the objects in the start node represent the elements in the array, defined in the Step 2
