Hello,

I read a csv file with the lookup command with a loop on the items:

   tasks:
     - set_fact:
         "{{ item.name }}": "{{ lookup('csvfile', '{{ item.csvvar }} 
file=vars/fvaltat.csv delimiter=; col=1') }}"
       with_items:
         - { name: 'KARAFHTTPTIMEOUT', csvvar: 'TOTO' }
         - { name: 'dbType', csvvar: 'DBTYPE' }

How to check the variable does exist and is different from space
I tried without success a fail ... when :
when: item.0 is not defined
when: item.name is not defined
when: item.name =='[]'
I tried to use a register variable but I cannot find the way to test the 
register variable content.

Thanks for your help
