Hi,

I am experiencing problems trying to parse an XML feed on Ubuntu - the  
same code works without any problems on OS X.

The code is roughly this:

============================================  
require ‘open-uri’  
require ‘rss’

# rss = RSS::Parser.parse(open(url).read, false)

On OS X it works fine. On Ubuntu:

/usr/local/lib/ruby/1.8/rss/parser.rb:474: available XML parser was not  
found in [[“rss/xmlparser”, :XMLParserParser], [“rss/xmlscanner”,  
:XMLScanParser], [“rss/rexmlparser”, :REXMLParser]].  
(RSS::XMLParserNotFound)

Am I missing something?

Cheers,  
Peter

Does this work?

% ruby -e ‘require “rexml/document”; p REXML::Version’

Thanks,
