Your syntax is incorrect. Try this instead.
${filename:endsWith('xml'):ifElse('XML','JSON')}

Subject: NiFi Expression Language in UpdateAttribute
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,
Russ
