Retrieving an array from a multidimensional array

My response from an API is coming in like:

[0] = "[Identity[id=95571, type=start, userId=d12345, processId=95567]]"
[1] = "[Identity[id=95572, type=start, userId=d67890, processId=95568]]"
etc

Lets call the above arr.

I want to retrieve all the userIds

I have tried:

all_users = arr.collect {|ind| ind[2]}

But this is obviously incorrect. What am I missing?

Thanks

Your array elements are strings, so can use string methods to extract parts from them, e.g.

arr.map { |e| e.match(/\[id=(/d+),/)[1] }
