-------------------------------------
Hi.
Thank you for this response. I do think your idea of relaxing the requirement
for a root tag even if there is only one record in the flow file is a good
idea. I do think that often someone will have a structure such as the one in my
example.
Relative to your second point, I am not sure I fully comprehend the expected
behavior as you describe it. I'd have expected that the inference engine give
me an inferred structure for the fltdMessage. Specifically this would include
values for the following:

> I've got a simple test flow as depicted below:

> The input XML is:
> !image-2019-04-24-13-41-26-860.png!
>
> The output JSON is almost correct, yet it is missing two critical fields
> (they both show up as "null". The null fields are
> {color:#ff0000}position{color} and {color:#ff0000}ncsmTrackData{color}. It is
> also missing all of the attributes on fltdMessage.

> The configuration of my ConvertRecord is:

> My XMLReader configuration is:

> Questions:
> # Why are these two fields null?
> # Why are all the fltdMessage attributes being ignored?
> It would seem that this is a bug, or at least a major shortcoming, in the
> schema inference capability. If there were a way for me to view the inferred
> schema, then I could use that as a starting point. However its not clear from
> the documentation how to view that schema.
