Question

I want to parse the line as this,

S1,F2  title including several white spaces  (abbr) single,Here<->There,reply

And I want the output as below,

1
2
title including several white spaces
abbr
single
Here22There  # identify <-> and translate it to 22; 
reply

I am wondering how to parse the line above?

Method 1.
I plan to split the whole line to four segments then parse the individual sub segments.

segment1. S1,F2

segment2. title including several white spaces

segment3. abbr

segment4. single,Here<->There,reply

Method 2.
I just write a complex regular expression statement to parse it.

Which method is more make sense for my practice?

Appreciated on any comments or suggestions.

Answer 1

Assuming your input be in the format specified you could use a regex like:

^S(\d+),F(\d+)\s+(.*?)\((.*?)\)\s+(.*?),(.*?),(.*)$
