Hello

I have one problem. I cannot use the library net/http to download the  
rss file. Why when I use it with rss file, it display nothing, but with  
other files, it works normally. Does anyone know how to do this? I don’t  
want to use open-uri library to work with the rss.

You know test open-uri against net/http to open one html file and  
display it back. I test and realize that open-uri seems to be slower  
than net/http. open-uri use 4.621 seconds and net/http use less than a  
second.

The following I use two different library ‘net/http’ and ‘open-uri’. But  
it returns different result. Why?

```
require 'net/http'

url = 

```

URI.parse(‘[Top stories - Google News](http://news.google.com/news?ned=us&topic=h&output=rss)’)  
req = Net::HTTP::Get.new(url.path)  
res = Net::HTTP.start(url.host, url.port) {|http|  
http.request(req)  
}  
puts res.body

```
require 'open-uri'

path = "http://news.google.com/news?ned=us&topic=h&output=rss"

content = ""
open(path) do |http|
   content = http.read
end
puts content

```

The last thing I want to say is great blog, but I want to ask you more  
“Does it still work on url like  
‘[Top stories - Google News](http://news.google.com/news?ned=us&topic=h&output=rss)’?” This is not a  
file how can it know it has modified or not?

Thanks

Chances are, you’re simply not calling net/http methods correctly, there  
is no reason at all why net/http wouldn’t work with XML. (In fact, I  
have it running in one of my applications.) Check your code against  
some samples in the RDoc. Why don’t you like open-uri?
