Data Stitch: Append and Assign for repeating elements by Jorge Herreria


Data Stitch has ASSIGN, APPEND and REMOVE operations. Some use-cases are easy to grasp; some others require a little thinking… On this blog I‘ll explain behaviors I deem they are not straightforward to derive the outcome for using Data Stitch in a OIC Orchestration:

· Assigning into unbounded elements (aka – Repeating Elements)

· Appending instances into an unbounded element and how to complete the data.

I assume you are familiar with XPath Expressions and XSD Schemas, because there is a lot a lingo in this post…

You will not see many screen shots. My goal is to give you the concepts so you become a good data “tailor?”

Expect some twisted humor here and there; more often that none.

I love this quote:  Perfection is boring; therefor laugh at your mistakes.


For Data Stitch Sentences

(TO XPath expression).OPERATION(FROM XPath expression)


($v1/ns0:customer/ns0:name).ASSIGN(“Jorge Herreria”)

On explanations you will see step/step/step/… in location paths. I’m going to omit the namespace prefixes, and just put the local-name on each step; looking to make it easy to read… However on actual XPathExpressions you’ll see prefixes. Read the complete article here.
