在Rails中将HTML添加到我的RSS / Atom提要

Question

The default rails XML builder escapes all HTML, so something like:

atom_feed do |feed|  
  @stories.each do |story|  
    feed.entry story do |entry|   
      entry.title story.title
      entry.content "<b>foo</b>"
    end  
  end  
end

will produce the text:

<b>foo</b>

instead of: foo

Is there any way to instruct the XML builder to not escape the XML?

Answer 1

turns out you need to do

entry.content "<b>foo</b>", :type => "html"

althought wrapping it in a CDATA stops it working.

Answer 2

entry.content "type" => "html" do
    entry.cdata!(post.content)
end

Answer 3

The special XML characters <, >, and & are converted to <, > and & automatically. Use the << operation to insert text without modification.
