Pattern for removing comments?

Hi,

in our codebase there are a lot of

/// <summary>
/// Service dependency.
/// </summary>
[ServiceDependency]
public ISomeService SomeService { get; set; }


Which we'd like to shorten to

[ServiceDependency]
public ISomeService SomeService { get; set; }

I created a simple pattern for this and it works, but the problem is that it also highlights the fixed properties that don't have a comment.
Is there a way to specify a pattern that is forced to match the comment? That is, when there's no comment, there's no match?

Thanks,
Steven
