* lib/rss/rss.rb (Hash#merge, Enumerable#sort_by): removed.
* lib/rss/rss.rb (RSS::RootElementMixin#to_xml): added. [ruby-talk:197284] We can convert RSS version easily like the following: rss10 = RSS::Parser.parse(File.read("1.0.rdf")) File.open("2.0.rss", "w") {|f| f.print(rss10.to_xml("2.0"))} * test/rss/test_1.0.rb: added #to_xml test. * test/rss/test_2.0.rb: ditto. * test/rss/rss-testcase.rb: added some helper methods that generates sample RSS 2.0. * sample/rss/convert.rb: added a sample script to convert RSS format. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/branches/ruby_1_8@10301 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
