I realize this is more a regexp question than a python question, but maybe one of the re object could help me:
I have wish to know how to _no_ match: This is but an example of the data I handle: xx xx xx xx xx xx xx [yy yy yy yy yy yy yy] (zz zz zz zz) I currently can retrieve the three group of logical data blocks with: l_str = 'xx xx xx xx xx xx xx [yy yy yy yy yy yy yy] (zz zz zz zz)' p = re.compile(r'([a-f-0-9\s]*) (\[[a-f-0-9\s]*\]) (\([a-f-0-9\s]*\))',re.IGNORECASE) #OK g = p.search(l_str) What I would rather do is. "get the data block that is _not_ between brackets or parenthesis i.e; 'xx xx xx xx xx xx xx' knowing that the intial string could be: [yy yy yy yy yy yy yy] xx xx xx xx xx xx xx (zz zz zz zz) Any clue ?
