Hello,

For the following piece of code:

#! /usr/bin/ruby

require ‘open-uri’  
require ‘rexml/document’  
require ‘rexml/xpath’

doc1 = open(“[Cricinfo Live Scores](http://www.cricinfo.com/rss/livescores.xml)”)  
puts doc1.class

doc2 =  
open(“[http://ws.audioscrobbler.com/1.0/artist/Autechre/toptags.xml](http://ws.audioscrobbler.com/1.0/artist/Autechre/toptags.xml)”)  
puts doc2.class

I get the following output:

moonwolf@trantor:~/ruby/lastfm$ ./scrape.rb  
StringIO  
Tempfile

The question I have is why openuri treats two similar entities as two  
different classes?

Thank you,

Jayanth
