I am attempting to map a response from a 3rd party call into a different structure using the DataMapper transform within Mule.
From the 3rd party we receive an array of items (amongst other things) and I want to map a single item within the array to an object (JSON). I receive an identifier for the item in the request which is available as an input argument.
My question is, how can I map the fields of the item based on the identifier?
Example XML response
<account> <accountNumber>1234567</accountNumber> <books> <book> <id>1</id> <title>Sample title1</title> <availableFrom>21-03-16</availableFrom> </book> <book> <id>2</id> <title>Sample title2</title> <availableFrom>21-03-16</availableFrom> </book> <book> <id>3</id> <title>Sample title3</title> <availableFrom>21-03-16</availableFrom> </book> </books> </account> Needs to become:
{ "person": { "accountNumber": 1234567, "selectedBook": { "id": 1, "title": "Sample title1" }, "otherBooks": [ { "id": 2, "title": "Sample title2" }, { "id": 3, "title": "Sample title3" } ] } } The id of the book selected is held in an inputArgument.bookId.
I can complete the mapping using an xpath rule for each of the fields, however, I have to hardcode the bookId in the xpath. Instead, I need to be able to substitute the actual id for the one provided (and available in the inputArgument).
xpath for title
/account/books/book[child::id=1]/title I have tried adding MEL to replace the id and various other fixes but nothing seems to work. Is there a way to substitute the bookId field.
Note: Due to client restrictions, I cannot use DataWeave.
