Yes, breaking it up would work, but that is not a solution for streams.

The regex is dead simple: /Authorization: Basic (.*)\ngrant_type=refresh_token/ "." does not match newline, so I'm basically looking two lines that conform to a template.

Specific cases can be transformed with some grep/awk magic, but IMO the concept of pattern matching against a stream is interesting regardless.

I missed the part where it was a stream. Also, is the grant_type guaranteed to be immediately after the token?
