+```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 }}"
+```
