Html formatting w/ Atom feeds

Hello,
I’m having a great time building some rss/atom feeds and I’ve been
quite successful until I hit the html formatting line of the Atom feed.

Here’s an example:

xml.instruct! :xml, :version=>“1.0”, :encoding=>“UTF-8”

xml.feed “xml:lang” => “en-US”, “xmlns” =>
'http://www.w3.org/2005/Atom ’ do
xml.title("flavor: #{@flavor} *title1: " + @feed.title)
xml.id(
“tag:#{request.host},#{Time.now.utc.year}:#{@feed.title}/#{@feed.title.downcase}”
)
xml.link('url: ’ + @ feed.guid) if @feed.guid
xml.author { xml.name “Author Name” }

 @entities.each do |entity|
   xml.entry do
     xml.title('title: ' + entity.title )
     xml.link("rel" => "alternate", "href" => url_for(url_for

:only_path => false, :controller => @this_controller, :action =>
@this_action, :id => entity.id))
xml.id(url_for(:only_path => false, :controller =>
@this_controller, :action => @this_action, :id => entity.id))
xml.updated("#{Time.now.utc.year}")

     xml.content "type" => "html" do
       xml.name entity.body   #-->>tried this - doesn't work
       xml.text! render(:partial => "shared/feed/entity", :entity =>

entity)–>>Tried this - doesn’t work

     end
   end
 end

end

If I could just get the
xml.content “type” => “html” do
end

section to work I would be home free.

Help!

xml.content “type” => “html” do
end

section to work I would be home free.

  1. You should be using xhtml for the content type. HTML assumes html
    escaped text. XHTML wants well formed HTML starting with a div tag:

http://tools.ietf.org/html/rfc4287#section-4.1.3

  1. You can use the #<< method to add raw xml to the xml object.
    Here’s how I do it in Mephisto:

(sanitize_feed_content is in here)

Rick - thanks for all your help.

I’m not quite sure I fully understand this. The closest I’m coming to
getting this displayed correctly is w/ this:

xml.content “type” => “xhtml” do
xml.content( “<div
xmlns=“http://www.w3.org/1999/xhtml”>#{entity.body}”)
end

This displays the info but does not render the html properly.

what am I missing?

Also, When I try this atom method in windows IE, it completely fails and
spits the output w/out any rendering at all.

Okay, just to be clear… I assumed from your code you want strongly
typed HTML, which is why I suggested the XHTML content type. In
Mephisto, I don’t run the content through tidy or anything and can’t
guarantee xhtml compliance, so I just use HTML for now. Use what you
like. I just wanted to highlight the difference between the two.

Also when I try rendering this feed as rss in windows IE it doesn’t even
respond.

Double Lordy.

Also - does anyone know if there are good functional tests to test the
validation of the rss and atom feed structures?

Thanks,

desperate

Look at how typo does it. I believe it calls the feed validator, or
checks for and uses the local feed validator lib if it exists.

Rick - I did try this:

xml.content “type” => “xhtml” do
xml << %{"

" + entity.body + “
” }
end

and it does render the html code properly but, for only one entry. In
other words, if I have 2 records in a database, only the first one is
getting displayed.

Weird. I’m close but missing something basic.

Thanks so much for your help.

Impossible to solve, this is, without an example of the result xml.
Well, on first glance, you didnt use << at all. sooo…

I also tried to render the xml.content section w/ a partial like this:

xml.content “type” => “html” do
xml.text! render(partial => “shared/feed/entity”, :entity => entity,
:xm => xml)
end

and the partial code would contain:

xm.entry ‘xml:base’ => home_url do
xm.title('title: ’ + entity.title )
xm.link(“rel” => “alternate”, “href” => url_for(url_for :only_path
=> false, :controller => @this_controller, :action => @this_action, :id
=> entity.id))
xm.id(url_for(:only_path => false, :controller => @this_controller,
:action => @this_action, :id => entity.id))
xm.updated("#{Time.now.utc.year}")
xm.author { xm.name “Author Name” }
xm << %{****#{entity.body}}
end

This still only prints out the first line.
