To me that looked more like a typo in the OP's ad-hoc data.

....not really given that line has an "@" but you get the point that there do
appear to be chains of multiple contiguous white spaces in the input....

I was aware of that when posting the suggestion. But you certainly agree
that given the OP's "specification" we can guess all day long, and build
bulletproof applications by guessing and assuming yet more details the
OP might have missed to tell us. That's why I've initially pointed out;

Note that "more data" may not contain the @ character for this to work.

Right, just thought it was worth pointing out since there was that
multiple-space example.
