What's the expected output of a file like the example above? Express the result you want as JSON.

Hi Magnus Bäck,

Thank you very much for helping me.

Output = elasticksearch  
but want to index on each of the line like ...  
Infodom  
RuleId  
BuildFlag  
InfoDate  
TaskID

But all these are on different lines on the same log file.

Please show an example event that you'd like to see. Do not _describe_ it. Show a concrete JSON example.
