Question

我有这样的输出。

“ vlan_output ['stdout_lines'] [0]”：[

 "VLAN Name                             Status    Ports", 
    "---- -------------------------------- --------- -------------------------------", 
    "1    default                          active    Po10, Po11, Eth1/44, Eth1/45", 
    "                                                Eth1/46, Eth1/47, Eth1/48", 
    "                                                Eth2/1, Eth2/2, Eth2/3", 
    "2    VLAN0002                         active    Po11, Po12, Po121, Eth1/1", 
    "                                                Eth1/2, Eth1/3, Eth1/4, Eth1/47", 
    "                                                Eth1/48", 
    "3    VLAN0003                         active    Po11, Po12, Po121, Eth1/1", 
    "                                                Eth1/2, Eth1/3, Eth1/4, Eth1/47", 
    "                                                Eth1/48", 
    "4    VLAN0004                         active    Po11, Po12, Po121, Eth1/1",

VLAN此处显示1,2,3,4 通常我们会删除一系列VLAN。删除后，我需要确保它们不在输出中。当然，实际输出中会有很多VLAN。通常我们会得到这样的范围3000-3005,3200,3400-3402

删除后，如何在此输出中搜索？在上面的输出中，输出中不应包含3000,3001,3002,3003,3004,3005,3200,3400,3401,3402（3000-3005 = 3001,3002,3003,3004,3005）。

我是Ansible的新手。不知道该怎么做。

以下不是完整的答案，而是您所发布问题的开始。

- hosts: localhost
  gather_facts: true
  tasks:
    - name: play
      set_fact:

    - debug:

输出->

**我已经使用查找来获取所需的信息，但是您可以使用寄存器变量的输出 **

Answer 2

我通过使用简单的正则表达式解决了这个问题

set_fact：vlan_regex =“ VLAN0003 \ s”
set_fact：run_vlan =“ {{vlan_output ['stdout_lines'] [0] | select（'search'，vlan_regex）| list}}”
调试：var = run_vlan

带有关键字后跟空格的简单正则表达式

在Ansible中以更大的输出搜索关键字
