Question : Retrieve title from URL in Ruby on Rails

I'm currently developing a web application in Ruby on Rails.
How can I retrieve website information such as title given a remote URL?
Examples of this can be seen in many places such as del.icio.us or reddit.com.

Thank you,

WJ

Answer : Retrieve title from URL in Ruby on Rails

Install all what is needed for mechanize or hypricot.
a gems install mechanize should do the work.
On debian you also have to install libopenssl-ruby
Then you just can write:
irb(main):002:0> require "rubygems"
true
irb(main):003:0> require "mechanize"
true
irb(main):004:0> agent = WWW:Mechanize.new
NoMethodError: undefined method `new' for :Mechanize:Symbol
      from (irb):4
      from /usr/local/lib/site_ruby/1.8/rubygems/user_interaction.rb:252
irb(main):005:0> agent = WWW::Mechanize.new
#b96b0 @keep_alive=true, @redirect_ok=true, @key=nil, @conditional_requests=true, @proxy_port=nil, @password=nil, @log=nil, @pluggable_parser=#echanize::PluggableParser:0x2ad7e34b95c0 @parsers={"text/html"=>WWW::Mechanize::Page}, @default=WWW::Mechanize::File>, @keep_alive_time=300, @pass=nil, @ca_file=nil, @proxy_addr=nil, @auth_hash={}, @user=nil, @cert=nil, @read_timeout=nil, @connection_cache={}, @proxy_pass=nil, @watch_for_set=nil, @digest=nil, @cookie_jar=#ze::CookieJar:0x2ad7e34b9660 @jar={}>, @history=[], @open_timeout=nil, @follow_meta_refresh=false, @proxy_user=nil, @user_agent="WWW-Mechanize/0.6.10 (http://rubyforge.org/projects/mechanize/)">
irb(main):006:0> page = agent.get("http://www.q-software-solutions.de/index.shtml")
# {url
  #HTTP:0x156bf1a57950 URL:http://www.q-software-solutions.de/index.shtml>}
 {meta}
 {title "Q Software Solutions"}

irb(main):007:0> page.title
"Q Software Solutions"
irb(main):008:0>

The last one is the title. It's easy to integrate that in any software you like. Quite handy, isn't it ;-)
