How about:


def test_it(str)
  num_lines = 4
  regexs = [/^start/, /something .*/, /^\s*$/, /^end/]

  lines = str.split("\n")
  return false if lines.length != num_lines

  match_results = lines.zip(regexs).collect{|line, regex| line =~ regex}
  match_results.all?
end





s1 =<<ENDOFSTRING
start
something else

end of data
ENDOFSTRING

s2 =<<ENDOFSTRING
start
something else

end of data
too many lines
ENDOFSTRING

s3 =<<ENDOFSTRING
start
something else
no match here
end of data
ENDOFSTRING

[s1, s2, s3].each do |str|
  puts test_it(str)
end

--output:--
true
false
false
