I am not up on this but in XML world I would have used XPath. I see there are both JsonPath and JsonQuery gems that seem to be geared for this kind of stuff.

I thought they just query...? Actually, I was just prototyping this in Ruby for porting to C#... I couldn't find anything in c# to do this either. I basically have .NET objects I'm serializing out to JSON then I want to take that JSON and use what I did here and then bring it back into .NET objects. This may not be my final solution (I may opt for reflection in the end) but I want to see this solution through.

They return the objects meeting the criteria and you set the property blindly. The query API I saw has a clone and replace API too which is good if concurrency is a concern.

Oh crap, in .Net there is a OSS Linq to JSON provider I see.

Any thoughts on how to do this better are most welcome! :)

Speaking as a non-rubyist, I notice that the last code sample features some pretty serious "pyramid building". Is the "opt out" approach not idiomatic? For comparison, I'd probably write it like this: http://pastebin.com/4P03Uqrq

My approach is definitely not idiomatic ruby so I think your point is completely valid.
