I have another question. By looking at my response, I am trying to go
deeper to access this value:  "Impression":{"Log":[{"uri"

I am attempting to do the following:


uri=
parsed['TOD']['AdBreaks']['AdBreak'][0]['Ad'][0]['MediaFile']['Impression']['Log'][0]['uri']

but it does not work. I get the following:  NoMethodError: undefined
method `[]' for nil:NilClass

This seems to work fine, which is a level above:

bitrate=parsed['TOD']['AdBreaks']['AdBreak'][0]['Ad'][0]['MediaFile']['bitrate']

Thanks
