How to write regex to match a key in yaml file?

Question

I have a yaml which looks like this..! Sonar by default providing sonar-yaml-plugin with some templates which accepts regex as input to verify particular key is present or not in .yml file.

I want regex to match entire key logging:file

 server:
   port: 8989
 logging:
    file: ./sample1.txt
    path: ./log

I have tried using (logging)(?s:.*?)(file) but its not validating when I use it in sonar-plugin.

I'm not so sure what you may want to match, but maybe this regex might help you to do so or design your desired expression:

^(logging:|\s+file:)(.+)

• This expression has a left boundary on start ^ .
• Your two words connected with an OR ( | )
• Then, matches everything after that using .+
• You can also add additional boundaries to it, however if you could add some real samples to your question, it would be easier to answer.
