I need to extract the indicted (bold & underlined) numbers from lines coming off web pages.

Of course I don't know ahead of time the location or length of the number.  What I do know
is the tag "Friends", and "Reviews", etc. In fact, it would be good to end up with

Value   Variable
108       Friends
151       Reviews
    5       Review Updates
  NA      First                 <-- assuming here that "First" did not show up on an line
etc.

Of particular trouble is line [7] which requires extracting 3 numbers 2022 (Useful), 1591 (Funny) and 1756 (Cool).
