Hi all,  
I'm not sure if this is possible or not. I'm collecting a lot of data and collecting it into a single line in a logfile.

For reference, this is the pre-log format

moduleName1  
----- InstalledVersion  
----- NewVersion  
----- Dependencies  
---------- Dependency1  
-------------pass/fail  
-------------versionGT  
-------------versionLT

moduleName2  
----- InstalledVersion  
----- NewVersion  
----- Dependencies  
---------- DependencyName  
-------------pass/fail  
-------------versionGT  
-------------versionLT  
---------- DependencyName  
-------------pass/fail  
-------------versionGT  
-------------versionLT  
---------- DependencyName  
-------------pass/fail  
-------------versionGT  
-------------versionLT

Logged results take the following format:

`puppet-windowsfeature,3.2.2,3.2.2;puppet-archive,puppet/archive,0.4.4,4.4.0,pass;5.0.0,pass; choria-mcollective_agent_puppet,2.3.2,2.3.3;puppetlabs-stdlib,puppetlabs/stdlib,4.22.0,6.1.0,pass;7.0.0,pass;puppetlabs-stdlib,puppetlabs/stdlib,4.22.0,6.1.0,pass;7.0.0,pass;`

So after the first three fields in the source message I have split on a ; to indicate the the start of the dependencies

If there is only one dependency then its easy:  
`(?<module_name>[^,]*),(?<installed_version>[^,]*),(?<latest_release>[^,]*);%{GREEDYDATA:dependencies}`

However, I'd like to create the same fields for each dependency, whether thats dep1\_DependencyName, dep1\_result, dep2\_DependencyName, dep21\_result etc.

The idea is to create a dashboard that presents our installed modules, whether there is an update available, and if so, whether dependencies are met.

Thanks,

Dave
