Transform matching nodes - Alumio Documentation

Applies data transformers to nodes within each entity that match the configured accessor. Use this step to reach into a repeating part of an item, such as the lines on an order or the addresses on a customer, and transform each matching part in place without touching the rest of the item. You choose how to find the nodes, optionally narrow them down with conditions, and then apply data transformers to just those nodes.

This step transforms parts of the items passing through a route, so it runs as part of a route rather than on its own. A configuration that applies a data transformer to every order line found by an accessor looks like this:

Field	Value
Accessor	An accessor pointing at the order lines
Node filters	(none)
Data transformers	One data transformer that sets a value

With this configuration, each item’s order lines are located by the accessor and the listed data transformer is applied to every line, while the rest of the item is left untouched.
