Hi Stefan

I look at the lines:

 def ExtractData(in_string, start_line, end_line):
     lstr = in_string.splitlines()
         j = 0 # a counter
         for i in lstr:
                 j = j+1

What is *not* clear to me:
1. Is your intendation consistent (only tabs or only always the same
number of spaces ?
2. after *lstr = in_string.splitlines()* you intend again. Why ? the
following line *j = 0 # a counter* belongs to the same block as one line
higher. So do you have an intendation too much ?

Regards
