Hi,

I think I know the answer is "can't do this in FME yet", but thought of asking anyway 🙂 Is there a syntax for constructing a predicate in JSON Query when used in a JSONExtractor or JSONFragmenter transformer? Basically I'm after getting to the data within complex JSON structures quicker and avoid having to fragment/flatten everything and then filter afterwards. Attached is an example: with a predicate, one would be able to get to the proper "Food" object in the array based on the predicate "Type"="Fruit", instead of having to flatten the whole thing, testing and filtering, then exploding again. Assuming this is not really possible, I also wrote a broader post in the Ideas section. Thanks.

That would be helpful to have, but from that documentation it appears that it is a function of a "[JSONata is a lightweight] query and transformation language for JSON data"

So safe would either have to build their own tools/functions/transformers to achieve similar results or license/include that language.

 

Regardless, have a thumbs up on your idea 👍

Thanks, you're absolutely right. I thought there was some kind of standard way to do JSON querying. Maybe I should have made reference to JSONPath perhaps...there seems to be definite room for improvement here, especially if you are using FME heavily to interact with web services.
