Question

I’m trying to extract properly some cookies from a web request.
Basically i have this string:

 str="""Cole_gal_langid=0; Expires=Sun, 14-Jul-13 20:37:22 GMT, Cole_gal_styleid=4; Expires=Sun, 14-Jul-13 20:37:22 GMT, Cole_gal_viewid=test; Expires=Sun, 14-Jul-13 20:37:22 GMT, Cole_gal_appid=gal; Expires=Sun, 14-Jul-13 20:37:22 GMT, Cole_gal_navk=common.invalidBookmark; Expires=Sun, 14-Jul-13 20:37:22 GMT, Cole_gal_trans=InvalidBookmark; Expires=Sun, 14-Jul-13 20:37:22 GMT"""

I want to remove all “Expires=Sun, 14-Jul-13 20:37:22 GMT,” entries within this string.
so this string become this:

str="""Cole_gal_langid=0; Cole_gal_styleid=4; Cole_gal_viewid=test; Cole_gal_appid=gal; Cole_gal_navk=common.invalidBookmark; Cole_gal_trans=InvalidBookmark;"""

I was thinking of using Re for this :

import re

str="""Cole_gal_langid=0; Expires=Sun, 14-Jul-13 20:37:22 GMT, Cole_gal_styleid=4; Expires=Sun, 14-Jul-13 20:37:22 GMT, Cole_gal_viewid=test; Expires=Sun, 14-Jul-13 20:37:22 GMT, Cole_gal_appid=gal; Expires=Sun, 14-Jul-13 20:37:22 GMT, Cole_gal_navk=common.invalidBookmark; Expires=Sun, 14-Jul-13 20:37:22 GMT, Cole_gal_trans=InvalidBookmark; Expires=Sun, 14-Jul-13 20:37:22 GMT"""

a = re.search('(Cole_gal_*.\=*)[^;]*', str)
if a:
   quote = "Regex found this: "+a.group(0)+"\r\n"
   print quote

Unfortunatly, i only get one result instead of all of the actual cookies

Any help or suggestion will be greatly appreciated.

Thanks !

Removes multiple occurrences of a pattern a job for re.sub:

>>> re.sub(r'Expires=.*?GMT([,;]|$)', '', s)
'Cole_gal_langid=0;  Cole_gal_styleid=4;  Cole_gal_viewid=test;  Cole_gal_appid=gal;  Cole_gal_navk=common.invalidBookmark;  Cole_gal_trans=InvalidBookmark; '
