Hi,
Context:
Structure JSON -> Map -> Structure XML

I wish hide XML element if element no matching with MapValues.

Here the MapValue of category

Here the Loop of category

Here the Input(JSON)

An idea?

Thank's for your help !!

Hi Eric,

I have tHmap with xml - jsonoutput.

in json output, some of the elements are empty/null and by default all empty elements are discarded in output and appearing in tRESTResponse.

i have applied not equal function in 'Emit' tab of element on jsonouput.

but if have multiple elements with empty values, only first element is empty is appearing through tHmap output and response.

is there a way to ensure all empty elements to pass through tHmap ?
