如果Ansible Facts注册变量有多行，该如何迭代循环

Question

我有以下多个文件，并已使用set_fact注册到变量。

文件_1

Topic  test-topic-15    Partition  0    Leader  2       Replicas  2,0,1 Isr  2,0
Topic  test-topic-15    Partition  1    Leader  0       Replicas  0,1,2 Isr  2,0
Topic  test-topic-15    Partition  2    Leader  1       Replicas  1,2,0 Isr  1
Topic  test-topic-15    Partition  3    Leader  2       Replicas  2,1,0 Isr  2,0
Topic  test-topic-15    Partition  4    Leader  0       Replicas  0,2,1 Isr  2,0
Topic  test-topic-15    Partition  5    Leader  1       Replicas  1,0,2 Isr  1

file_2

Topic  test-topic-16    Partition  0    Leader  2       Replicas  2,0,1 Isr  2,0
Topic  test-topic-16    Partition  1    Leader  0       Replicas  0,1,2 Isr  2,0
Topic  test-topic-16    Partition  2    Leader  1       Replicas  1,2,0 Isr  1
Topic  test-topic-16    Partition  3    Leader  2       Replicas  2,1,0 Isr  2,0

file_3 ..........

示例代码

 - name: register to a 2 variable
    set_fact:
      contents_2: "{{ lookup('file','/tmp/all_{{ item }}') }}"
    with_items:
      - "{{ available_topics.stdout.split('\n')  }}"
    register: contents_3

  - name: to a file 4
    lineinfile:
      line: '"topic_name": "{{ item.split()[1] }}", "partition_no": "{{ item.split()[3] }}", "leader": "{{ item.split()[5] }}"", "replicas": "{{ item.split()[7] }}"", "isr": "{{ item.split()[9] }}"'
      path: "/tmp/some_file_name_{{ item.split()[1] }}"
      create: yes
    with_items: "{{contents_3.results|map(attribute='ansible_facts.contents_2') | list}}"

使用上述代码，我得到的输出如下，其中仅包含每个输入文件的第一行数据。

第一个文件输出

"topic_name": "test-topic-15", "partition_no": "0", "leader": "2", "replicas": "2,0,1", "isr": "2,0"

第二个文件输出

"topic_name": "test-topic-16", "partition_no": "0", "leader": "2", "replicas": "2,0,1", "isr": "2,0"

但是我希望输出如下。当我刚接触Ansible时，能否请您帮助如下所示的输出？

第一个文件输出

"topic_name": "test-topic-15", "partition_no": "0", "leader": "2", "replicas": "2,0,1", "isr": "2,0"
"topic_name": "test-topic-15", "partition_no": "1", "leader": "0", "replicas": "0,1,2", "isr": "2,0"
"topic_name": "test-topic-15", "partition_no": "2", "leader": "1", "replicas": "1,2,0", "isr": "1"
......

第二个文件输出

"topic_name": "test-topic-16", "partition_no": "0", "leader": "2", "replicas": "2,0,1", "isr": "2,0"
"topic_name": "test-topic-16", "partition_no": "1", "leader": "0", "replicas": "0,1,2", "isr": "2,0"
