[julia-users] Possible to use filter! on a child dict within a parent dict, to remove the entire parent dict if condition in child is met?

[Ian Butterworth]

I have a dict containing both key+value pairs, and key+[array of dict] 
pairs.

Can I use filter! to remove the entire parent dict if condition in child is 
met?

i.e. 

If measurements[uniqueentrykey]["studyid"] == "bad study" then remove 
measurements[uniqueentrykey]

Thanks
