Filtering Nested JSON Arrays

Posted on by ATarrant

Hi all,

I have a JSON (see below) which contains a series of form submissions. Each submission includes a formSubmissionId and a series of fields with their corresponding fieldReferenceId and fieldValue.

What I want to do is produce a new array listing all the records where the fieldReferenceId '18c837cd-1dae-4961-9164-3de23e9c954b' has a fieldValue of 'a1GJ7000000sZ9cMAE'.

In the example JSON below, there are two submitted records. I want to extract only the second one, because it has a fieldValue of 'a1GJ7000000sZ9cMAE' for the fieldReferenceId '18c837cd-1dae-4961-9164-3de23e9c954b'.

Due to the potential size of the data, I believe using a 'FilterArray' would be more efficient than nested 'Apply To Each' actions.

I really appreciate any help with this.

Thanks.

Hi Chriddle,
I was just using your expression, and I want to change the static
fieldValue="a1GJ7000000sZ9cMAE"
To a dynamic value earlier within the same flow. The reference to the dynamic value is:
triggerBody()?['body']?['VisitID']
Would you be able to tweak y our expression to accept this? I've tried with the expression below, and whilst it runs, it doesn't return any records, when it should:
xpath( xml( json( concat( '{"Root":', outputs('GetDataCollector'), '}' ) ) ), '//data[fields[fieldReferenceId="18c837cd-1dae-4961-9164-3de23e9c954b" and fieldValue=triggerBody()?['body']?['VisitID']]]' )

You have to concat this into the xpath string:

xpath( xml( json( concat( '{"Root":', outputs('Compose'), '}' ) ) ), concat( '//data[fields[fieldReferenceId="18c837cd-1dae-4961-9164-3de23e9c954b" and fieldValue="', triggerBody()?['body']?['VisitID'], '"]]' ) )
