Hi,
I'm fairly new in Python and I haven't used the regular expressions
enough to be able to achieve what I want.
I'd like to select terms in a string, so I can then do a search in my
database.
query = ' " some words" with and "without quotes " '
p = re.compile(magic_regular_expression) $ <--- the magic happens
m = p.match(query)
I'd like m.groups() to return:
('some words', 'with', 'and', 'without quotes')
Is that achievable with a single regular expression, and if so, what
would it be?
Any help would be much appreciated.
Hi,
I think re is not the best tool for you. Maybe there's a regular
expression that does what you want but it will be quite complex and hard
to maintain.
I suggest you split the query with the double quotes and process
alternate inside/outside chunks. Something like:
import re
def spulit(s):
inq = False
for term in s.split('"'):
if inq:
yield re.sub('\s+', ' ', term.strip())
else:
for word in term.split():
yield word
inq = not inq
for token in spulit(' " some words" with and "without quotes " '):
print token
Cheers,
