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

Hi Eric,

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 ?
