@redhatrises #291 forced a rebase of this

[shawndwells]

components and standard iterations are very similar. Could this be condensed into a for each loop?

e.g.

    arrayOpenControl := [2]string{"components", "standards"}

    for index,element := range arrayOpenControl{
        if len(p.element) > 0 {
           .... do stuff
        }     
    }   
}

@shawndwells this actually would probably be a separate function as it deals with more than just strings.
I was hoping to avoid code cleanup in these type of PRs because of how big they are.

Tracked in #295

Sounds good. Thanks for opening the ticket to track.
