It's hard to be certain exactly what you're
looking for, I'm going to assume that you are
looking for a specific keyword and that the text
following is fairly free form.
my $keyword = "BASKET";
$data =~ /^($keyword\n\n.+)$/m;
This looks for the keyword followed by two
newlines, and whatever else is on that line. It
will not match if the line following the two
newlines is blank. The m at the end of the
pattern specifies multi-line matching i.e. the $
will match before any newline, not just at the end
of the string.
This answer assumes that $data contains all of
the text you are trying to search, not just a
single line.
