That solves confusion I had after and despite reading the NiFi
Expression Language documentation. Having written documentation before,
I get why it's never ending and danger-fraught to write "bigger"
examples in such documentation, and we resist doing it, but that's what
I needed to clear up in my head the combination of how the two
constructs, endsWithand ifElse, work together.
Many thanks!

I wnat to create an attribute, format-type, which I hoped would be set
based on the in-coming flowfile name:
${ ${filename:endsWith( 'xml' )} : ifElse( 'XML', 'JSON' ) }
If the in-coming flowfile name is /sample.xml/, the result is
nevertheless and always
format-type = JSON
I want it to be XML, obviously. What have I screwed up in my NEL syntax?
(Yes, I have tried taking out all the white space.)
Thanks,
