Loading XML file from web

ruby-talk
1

I am looking to open an xml file from the web.

The xml file is located at http://www.digg.com/rss/index.xml

I want it to work something like this...

require "rexml/document"
include REXML
file = File.new( "http://www.digg.com/rss/index.xml" )
doc = Document.new file

BUT!
This line doesn't work: file = File.new(
"http://www.digg.com/rss/index.xml" )

How do i load an xml file from the web?
Thanks!

This is pretty much straight from the documentation of Net::HTTP

require 'net/http'
Net::HTTP.start('www.digg.com', 80) { |http|
  response = http.get('rss/index.xml')
  response.body # this is the text of www.digg.com/rss/index.xml
}

so simply now create an instance of Document with the text
response.body (I haven't tried this out myself, but should work)

Or use open-uri.

How about this....

require "open-uri"
open("http://www.digg.com/rss/index.xml") do |file|
  file.each_line {|line| puts line}
end

This will just dump the contents of the file.

Thank you, yours was the one which worked. The others caused parsing
errors.

Thanks!
