Rails 与 XML - RXML

以下是使用 Rails 创建 XML 的示例 −

xml.instruct!             # <?xml version = "1.0" encoding = "UTF-8"?>
xml.comment! "a 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
	
   xml.author do
      xml.name "Jens-Christian Fischer"
      xml.email "jcfischer@gmail.com"
   end

   @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
