match.rb

# vim:set fileencoding=utf-8:

string = "http://www.example.com/hoge/fuga"

/(?<protocol>[a-z]+):\/\/(?<server>[^\/]*)\/(?<path>.*)/ =~ string
p [protocol, server, path]  # => ["http", "www.example.com", "hoge/fuga"]

m = /(?<protocol>[a-z]+):\/\/(?<server>[^\/]*)\/(?<path>.*)/.match(string)
p m
#=> #<MatchData "http://www.example.com/hoge/fuga" protocol:"http" server:"www.example.com" path:"hoge/fuga">

p m[:protocol]  #=> "http"
p m["protocol"] #=> "http"

p [m[:protocol], m[:server], m[:path]] #=> ["http", "www.example.com", "hoge/fuga"]
