Hello,

I wonder if someone would be able to help.

Through necessity I'm learning Ruby and trying to write my own script
and while I am getting there and grasping things more, I'm still on
first rung of the ladder and finding things difficult so please be
patient

Part of my script involves opening a telnet session and then sending a
whois request that returns a lot of text ...

I've managed to get to the point where I have the reply stored in a
variable but what I would now like to do is parse the variable for bits
of the information and I have read and read but can't find something
that I seem to be able to understand.

I have attached a text file with the data that my variable holds and I
need to parse out things like the "Renewal date:" and "Registration
status:". Would anyone be able to offer me some help on how I should go
about parsing.

TIA

Warby

You should a bit about regular expressions. If the text has "simple"
rules, regexes are usually enough to extract the pieces of data you
need. In your case, for example:

irb(main):001:0> data =<<EOF
irb(main):002:0" Domain name:
irb(main):003:0" suburbia.co.uk
irb(main):004:0"
[...]

irb(main):053:0> m = data.match(/Renewal date:\s+(.*)/)
=> #<MatchData "Renewal date: 28-Oct-2009" 1:"28-Oct-2009">
irb(main):054:0> m[1]
=> "28-Oct-2009"

If your case is as simple as this, the above solution could be enough.

Hope this helps,

Jesus.

Thank you, I'll try your suggestion.

Second, you'll have better luck on the Rails mailing lists:
http://rubyonrails.org/community

While every Rails user uses Ruby, not every Ruby user uses Rails.
