Hey Halberom,

Thanks for sharing this , BTW could you please share the way to process the each element of array and then printing them in a loop ;

I have created an array "path" ,

• set_fact: path="{{ result.files|map(attribute='path')|list}}"

now i am trying to apply "dirname" filter on each element of array but its getting applied only to last element .

• set_fact: myvar="{{ item | dirname}}"
  with_items: "{{ path }}"

• debug: var=myvar

Kind Regards,

Hi Ritesh-Sharma,

I am also facing this issue too.

You can chain several filters:

set_fact:
  myvar: "{{ result.files | map(attribute='path') | map('dirname') | list }}"
