Ansible。 解析 yaml。 从字符串中获取值

Question

How do I get the mac address 00 50 79 66 68 04 from the string that is contained in the following variable?

"oid.stdout_lines": [
       "iso.3.6.1.2.1.17.4.3.1.1.0.80.121.102.104.4 \"00 50 79 66 68 04 \""
   ]

Answer 1

Use regex_replace . For example

  _regex: '.*"(.*)"'
  _replace: '\1'
  mac: "{{ oid.stdout_lines|first|regex_replace(_regex, _replace)|trim }}"

gives

  mac: 00 50 79 66 68 04
