Dear vaia,


Sale order fail to sync when it contain Generic Product. ....need to little
investigate about it.
This is a issue which is occurred if any product have salePrice of greated
then 2 decimal value like 33.34500 etc.
Now POS only use @ decimal values like 33.34 so please aware about this
about configuring prism to have always 2 decimal digits.

You can get it like so:

import re

with open(file, 'r') as f:
    print re.findall(r'^.*?(?=On \w{3},)', f.read(), re.DOTALL)[0].strip()

Output:

Regex:

^.*?(?=On \w{3},) - Match everything from starting till first occurence of On \w{3}, pattern.

re.DOTALL will make the . match newline characters as well.
