Ansible 替换正则表达式前后的多行-解网

问：

我正在使用 ansible tower 修改文件 .baroc，使用用户为正则表达式提交的变量。

对于exampe，这是要修改的文件：

AUTOMATION;
groupe_affectation='Test'';
msg_exception='APPLI 1';
mc_long_msg='eKBX';
commentaire='Automatic';
END

AUTOMATION;
groupe_affectation='Test'';
msg_exception='APPLI 1';
mc_long_msg='eKB42';
commentaire='Automatic';
END

AUTOMATION;
mc_service='.\* - PRE-PRODUCTION';
application_infogerant='toto|test';
mc_long_msg='eKB12345';
mc_host='';
mc_object_class='';
mc_object='';
mc_parameter='';
msg='';
groupe_affectation='EXPLOITATION_APPLICATIONS-TOTO';
commentaire='DT123';
END

\########################################################################################################################################################################

# TOTO - Affectation CA

\########################################################################################################################################################################

# TOTO - CTRLM

AUTOMATION;
mc_long_msg='eKB007';
ctm_application='test.';
ctm_group='';
ctm_jobname='';
ctm_datacenter='';
ctm_nodeid='';
ctm_msg='';
groupe_affectation='MCO_test';
commentaire='DT01';
END
AUTOMATION;
groupe_affectation='SUPPORT';
msg_exception='APPLI 4';
mc_long_msg='eKB007';
commentaire='Automatic';
END

在这个问题上，我想删除整个集团：

AUTOMATION;
groupe_affectation='Test'';
msg_exception='APPLI 1';
mc_long_msg='eKB42';
commentaire='Automatic';
END

这是我的剧本：

---

- name: Suppression d'un eKB au fichier Paperboy
  hosts: localhost
  become: yes

  tasks:

  - name: Vérifier si le eKB est bien présent ########Check if the eKB is present
    lineinfile:
    path: /exemple/of/a/PATH.baroc
    line: "eKB042"
    state: absent
    check_mode: yes
    register: presence

  - name: Arrêter le playbook si le eKB n'est pas présent ########Stop the playbook if the eKB is absent
    fail:
    msg: "L'eKB042 n'est pas présent dans le fichier baroc."
    when: presence.changed

  - name: Copie du fichier baroc dans le old #Backup
    ansible.builtin.copy:
    src: /exemple/of/a/PATH.baroc
    dest: /exemple/of/an/old/PATH.baroc.soway.{{ ansible_date_time.iso8601_basic }}

  - name: Suppression de la règle au fichier PAPERBOY.baroc ########Delete bloc
    ansible.builtin.replace:
    path: /exemple/of/a/PATH.baroc
    after: 'PAPERBOY(?:(?!PAPERBOY)(.|\\n))*eKB0031549'
    before: 'END(?!(.|\\n)eKB0031549)'
    regexp: '^.*(eKB042).$'
    replace: '! '
    ...

问题是它开始了最后一次品尝而没有结束...... 我知道最后一个任务之前的所有内容都可以正常工作，因为我将其用于其他目的（添加行以制作新的 eKB），并且它工作正常。我认为问题出在我使用的正则表达式上......即使在 regex101 上也没关系。

因此，我愿意将集团从 AUTOMATION 删除到 END（我认为是最佳实践），或者如果太困难，请删除 eKB 之前的 3 行和 eKB 之后的 2 行;因为 playbook 将始终用于删除类似的自动化块。较长的块不会以这种方式删除，也不会具有相同的 eKB 编号

感谢您的帮助

and parse the content

Modify what you want and write the block

    - debug:

          {% for k,v in i.items() %}

          {{ k }};
          {% else %}

Q: Delete the entire bloc

A: Put the blocks you want to delete into a list

    blocks_del:
      - |
        AUTOMATION;
        groupe_affectation='Test'';
        msg_exception='APPLI 1';
        mc_long_msg='eKBX';
        commentaire='Automatic';
        END

Convert the blocks to lines

    lines_del: "{{ blocks_del|map('split')|map('join', ' ') }}"

    lines: |
      {% filter from_yaml %}
      {% for i in test %}
      {% for k,v in i.items() %}
      {% if loop.index == 1 %}
      - {{ k }};
      {% else %}
        {{ k }}='{{ v }}';
      {% endif %}
      {% endfor %}
        END
      {% endfor %}
      {% endfilter %}

and write the difference between the lists

    - debug:
        msg: |
          {% for i in lines|difference(lines_del) %}
          {% for j in i|split('; ') %}
          {{ j }}{% if not loop.last %};{% endif +%}
          {% endfor %}

          {% endfor %}

You can simplify the code by creating a list of dictionaries you want to delete. For example,
blocks_del:
- AUTOMATION: ''
commentaire: Automatic
groupe_affectation: Test'
mc_long_msg: eKBX
msg_exception: APPLI 1
- PAPERBOY: ''
commentaire: Automatic
groupe_affectation: Test'
mc_long_msg: eKB42
msg_exception: APPLI 1

Then, you can directly iterate the difference
test|difference(blocks_del):
- AUTOMATION: ''
application_infogerant: toto|test
commentaire: DT123
groupe_affectation: EXPLOITATION_APPLICATIONS-TOTO
mc_host: ''
mc_long_msg: eKB12345
mc_object: ''
mc_object_class: ''
mc_parameter: ''
mc_service: .\* - PRE-PRODUCTION
msg: ''
- AUTOMATION: ''
commentaire: DT01
ctm_application: test.
ctm_datacenter: ''
ctm_group: ''
ctm_jobname: ''
ctm_msg: ''
ctm_nodeid: ''
groupe_affectation: MCO_test
mc_long_msg: eKB007
- AUTOMATION: ''
commentaire: Automatic
groupe_affectation: SUPPORT
mc_long_msg: eKB007
msg_exception: APPLI 4}

Hello, thanks for your answer. So there is two things to precise : - I have put the wrong entry to delete from the fil, PAPERBOY shouldn't be there, it should be as all the others Automation. I have replace the sentence but it should be always the same word in the begening and at the end of the file. - The user that want to delete a bloc doesn't know the content of the file, he only knows the eKB number. So he should only put as variable eKBXXX Moreover the file should be modified, the sections with " ####### XX " should be maintained

上一个：正则表达式匹配撇号（'）中的破折号（-）

下一个：如果需要，使用 RegExp 在开头只得到一个“-”
