  20. Hash print ({:name=>'song', :lname=>'lee'}.to_xml)

  21. Hash.from_xml h = Hash.from_xml(File.new("abc.xml"))

  22. Lab x = <<-EOT <export> <mineral>20_000</mineral> <electronic>300_000</electronic> <fishery>50_000</fishery> </export> EOT Hash.from_xml(x)

  23. Builder xml.instruct! xml.comment! "a comment" xml.feed "xmlns" => "http://www.w3.org/2005/Atom" do xml.title "My Atom Feed" xml.subtitle h(@feed.subtitle), "type" => 'html' xml.link url_for( :only_path => false, :controller => 'feed', :action => 'atom' ) xml.updated @updated.iso8601 @entries.each do |entry| xml.entry do xml.title entry.title xml.link "href" => url_for ( :only_path => false, :controller => 'entries', :action => 'show', :id => entry ) xml.id entry.urn xml.updated entry.updated.iso8601 xml.summary h(entry.summary) end end end
