hi all.

im very new to ruby and im not sure how to do this the easiest way in  
ruby. i want to read the content from e.g. “[www.spiegel.de](http://www.spiegel.de)” and just  
this line

and from this line the “title” and the “href”

since the order in “link” is not sure, it doesnt look like regexp is the  
first choice. and i couldn’t find a HTML::Parse.

is the best way to do so??)

Another possibility is scRUBYt!:

==========================================  
require ‘rubygems’  
require ‘scrubyt’

feed\_data = Scrubyt::Extractor.define do  
fetch ‘[http://www.spiegel.de/](http://www.spiegel.de/)’

link “//link[@rel=‘alternate’]” do  
title “title”, :type =\> :attribute  
href “href”, :type =\> :attribute  
end  
end

# puts feed\_data.to\_xml

output:

==========================================

 SPIEGEL ONLINE als RSS-Feed http://www.spiegel.de/schlagzeilen/rss/index.xml ==========================================

or, to\_hash:

# ========================================== [{:title=\>“SPIEGEL ONLINE als RSS-Feed”, :href=\>“[DER SPIEGEL - Schlagzeilen](http://www.spiegel.de/schlagzeilen/rss/index.xml)”}]

Cheers,  
Peter

Hm yeah, but the downside (as of the recent version - it’ll be fixed in  
the next one) is that the installation process is somewhat… hmm… not  
that easy (mainly if you are on win32). If you still decide to go for  
scRUBYt!, we can talk on #scrubyt @ [irc.freenode.net](http://irc.freenode.net) or you can ask your  
questions in the forum ([http://agora.scrubyt.org](http://agora.scrubyt.org)).

Cheers,  
Peter
