that matches lines that start with '..'  or '..' or '----'
so whatever else is going on, there is no need to repeat.

If that is what is literally found in the file then
line.startswith(('R|1|^^^','O|1|'))
ought to match them.  But if that syntax means something else, i.e
an R, followed by a 1, followed by any 4 characters, then you will
have to explain what the syntax means.
