Ansible 有没有办法在每次循环的时候把值存入数组？

Question

我有一个 ansible-playbook，旨在显示来自域控制器内 DNS 服务器的特定主机的 A Record。这是我在 Ansible-Playbook 上所做的：

使用powershell获取DNS服务器A记录相关信息。
将其保存为名为 test_var.
将变量test_var的内容逐行划分
检索包含我要查找的字符串 host 的重要行。
把那些重要行的重要属性取下来，显示为msg。

代码如下：

# hostname and domain are necessary
---
- hosts: all
  gather_facts: no
  vars:
    search_name: "{{hostname}}"
  tasks: 

    - name: powershell query
      win_shell: "Get-DnsServerResourceRecord -Name '{{hostname}}' -ZoneName '{{domain}}' -RRType A"
      register: result1
      when: (hostname is defined) and (domain is defined)
      
    - set_fact:
        test_var: "{{ result1.stdout_lines }}"
    
    - name: pickup lines
      set_fact:
        important_lines: "{{ important_lines |default([]) + [item] }}"
      with_items:
      - "{{ test_var }}"
    
    - name: find the line
      set_fact:
        target_line: "{{item}}"
      when: item|trim is search(search_name)
      loop: "{{ important_lines | flatten(1) }}"

    - name: get all attributes
      set_fact:
        attribute_record: "{{ target_line.split()[1]|trim}}"
        attribute_type: "{{ target_line.split()[2]|trim}}"
        attribute_timestamp: "{{ target_line.split()[3]|trim}}"
        attribute_timetolive: "{{ target_line.split()[4]|trim}}"
        attribute_ipaddress: "{{ target_line.split()[5]|trim}}"
        
    - name: print results
      debug:
        msg: "name: {{search_name}}, Ip Address: {{attribute_ipaddress}}"

这是我的 DNS 服务器配置：

结果如下(host=test1):

但是，我有一个问题。在运行循环的 Find the line 任务中，target_line 变量仅存储任务末尾的最后一行。所以，当执行 print results 任务时，只会显示最后的主机和 IP 地址。问题是，有没有办法在每次循环发生时将每一行存储在一个数组中？这样，我就可以调用数组的内容来一一显示了。谢谢。

这是我得到的解决方案：

# hostname and domain are necessary
---
- hosts: all
  gather_facts: no
  vars:
    correct_line: []
    search_name: "{{hostname}}"
  tasks: 

    - name: powershell query
      win_shell: "Get-DnsServerResourceRecord -Name '{{hostname}}' -ZoneName '{{domain}}' -RRType A"
      register: result1
      when: (hostname is defined) and (domain is defined)
      
    - set_fact:
        test_var: "{{ result1.stdout_lines }}"
    
    - name: pickup lines
      set_fact:
        important_lines: "{{ important_lines |default([]) + [item] }}"
      with_items:
      - "{{ test_var }}"
    
    - name: find the line
      set_fact:
        correct_line: "{{correct_line + [item]}}"
      when: item|trim is search(search_name)
      loop: "{{ important_lines | flatten(1) }}"
      
    - name: print results
      debug:
        msg: "name: {{item.split()[0]|trim}}, Ip Address: {{item.split()[5]|trim}}"
      loop: "{{ correct_line | flatten(1) }}"

结果如下：

Is There a Way to Have a Value Stored in an Array Every Time the Loop Occurs in Ansible?
