Ansible regex_findall multiple strings

Ansible regex_findall multiple strings

In Ansible, you can use the regex_findall filter to find multiple strings using a regular expression. The regex_findall filter extracts all occurrences of a pattern in a string. Here's an example playbook demonstrating how to use regex_findall with multiple strings:

--- - name: Use regex_findall with multiple strings hosts: localhost gather_facts: false tasks: - name: Define a sample string set_fact: sample_string: "This is a sample string with multiple patterns: abc123, def456, and xyz789." - name: Use regex_findall to extract multiple patterns debug: msg: "{{ sample_string | regex_findall('abc\\d+|def\\d+|xyz\\d+') }}"

In this example:

  • The sample_string variable contains the input string with multiple patterns.
  • The regex_findall filter is used to extract all occurrences of the specified patterns (abc\\d+, def\\d+, xyz\\d+).
  • The debug task outputs the result.

Make sure to escape the backslashes (\) in the regular expression since Ansible uses YAML, and backslashes need to be escaped.

Adjust the patterns in the regex_findall filter according to your specific use case. The patterns are separated by the | (pipe) character, indicating a logical OR operation.
