Hi!

I have this String, gotten from the set-cookies value of an HTTPResponse (from a post call):

KEY1=VALUE1; Path=/, KEY2=VALUE2; Domain=.somedomain.net; Expires=Mon, 24-Jan-2005 19:40:10 GMT;
Path=/, KEY3=VALUE3; Domain=e-messenger.net; Expires=Mon, 24-Jan-2005 19:40:10 GMT; Path=/

How can I extract each KEY,VALUE pair? I'm currently TRYING to use the scan String method, but I've
never been that good with regular expressions... any help?

Bye and thanks!

I have this String, gotten from the set-cookies value of an HTTPResponse
(from a post call):

KEY1=VALUE1; Path=/, KEY2=VALUE2; Domain=.somedomain.net; Expires=Mon,
24-Jan-2005 19:40:10 GMT;
Path=/, KEY3=VALUE3; Domain=e-messenger.net; Expires=Mon, 24-Jan-2005
19:40:10 GMT; Path=/

How can I extract each KEY,VALUE pair? I'm currently TRYING to use the
scan String method, but I've
never been that good with regular expressions... any help?

input = 'KEY1=VALUE1; Path=/, KEY2=VALUE2; Domain=.somedomain.net; ' +
'Expires=Mon, 24-Jan-2005 19:40:10 GMT; Path=/, KEY3=VALUE3; ' +
'Domain=e-messenger.net; Expires=Mon, 24-Jan-2005 19:40:10 GMT; Path=/'

pkv = Regexp.new(';?\s*(?ath=([^,]+),?)?\s*(?[^=]+)=([^;]+))?')
input.scan(pkv) do |path, key, value|
puts "path=#{path} key=#{key} value=#{value}"
end

Produces:

path= key=KEY1 value=VALUE1
path=/ key=KEY2 value=VALUE2
path= key=Domain value=.somedomain.net
path= key=Expires value=Mon, 24-Jan-2005 19:40:10 GMT
path=/ key=KEY3 value=VALUE3
path= key=Domain value=e-messenger.net
path= key=Expires value=Mon, 24-Jan-2005 19:40:10 GMT
path=/ key= value=
path= key= value=

The last line is annoying, but hard to fix. Since you can have either
Path alone, or Key=Value alone, or both together, it's hard to avoid
matching the fourth option, which is neither Path nor Key=Value, i.e.
the empty string. That's what I get at the end of the scan, but it's
easy to ignore that case.

Whoa! Thank you very much! Now I'll try to understand that regexp, and learn from it. Thanks for
your precious time
