Regular expression for different date formats in Python

[undesputed.hackerz]

Hello Developers,

I am a beginner in python and need help with writing a regular expression for date and time to be fetched from some html documents. In the following code I am walking through the html files in a folder called event and printing the headings with h1 tag using beautifulsoup. These html pages also contains different formats of date and time. I want to fetch and display this information as well. Different formats of date in these html documents are:

21 - 27 Nov 2012
1 Dec 2012
30 Nov - 2 Dec 2012
26 Nov 2012

Can someone help me out with fetching these formats from these html documents ?
Here is my code for walking through the files and fetching h1 from those html files:


Code:


import re
import os
from bs4 import BeautifulSoup

for subdir, dirs, files in os.walk("/home/himanshu/event/"):
for fle in files:
path = os.path.join(subdir, fle)
soup = BeautifulSoup(open(path))

print (soup.h1.string)

#Date and Time detection

Would the "parser" module from the third-party dateutil module work for you?

http://pypi.python.org/pypi/python-dateutil
http://labix.org/python-dateutil#head-c0e81a473b647dfa787dc11e8c69557ec2c3ecd2

I don't believe the library is updated for Python 3 yet, sadly. But I
bet it could be ported fairly easily. I think it's pure python.

Hi,
the following pattern seems to match all of your examples,

(\d{1,2} )?(Nov|Dec)?( ?- )?(\d{1,2}) (Nov|Dec) (\d{4})

however, it doesn't look like very robust - of course, you have to add
the remaining months' abbreviations and check on the (parts of the)
HTML documents, you are interested in.

hth,
vbr

dateutil supports 3.x since version 2.0.
