+```YAML
+- name: First loop
+ loop: {{ blaat }}
+ register: loooped
+ ...
+
+- name: Second loop
+ loop: {{ loooped.results }}
+ when: item.skipped is not defined
+```
+
+this loops over results of prior loop only but does not process any skipped results.
+
+In case the results array contains another array that we want to loop over, for example when we did a shell command in a loop we can use extract:
+```
+- name: Print magic
+ ansible.builtin.debug:
+ msg: "{{ ['stdout_lines'] | map('extract', item) }}"
+ loop: "{{ magic.results }}"
+```
+
+A cool example of this in practice:
+```
+- name: Print blockpull command
+ ansible.builtin.debug:
+ msg: "virsh blockpull {{ ['stdout_lines'] | map('extract', item) | list | flatten | join(' ') }}"
+ loop: "{{ domain_and_disk_paths.results }}"
+ loop_control:
+ label: "{{ inventory_hostname }}"
