I suspect this has nothing to do with regular expressions, but it's just
about string management.
The first thing you want to do is verify that the text you are reading
in from the file is the same as the text you have in triple quotes. So,
write a program like this:
test='''<long string elided>'''
datafile=open('a.txt','r')
data_array=''
for line in datafile:
data_array=data_array+line
print test == data_array
If that prints True, then you've got the same text in both cases (and
you can go on to looking for other problems). I suspect it will print
False, though. So, now your task is to figure out where those two
strings differ. Maybe something like:
for c1, c2 in zip(test, data_array):
print c1 == c2, repr(c1), repr(c2)
and look for the first place they're not the same. Hopefully that will
give you a clue what's going wrong.
