Question

Ruby. I use standart builder to generate rss. My builder file is:

xml.instruct! :xml, :version => "1.0"
xml.rss(:version => "2.0") {
xml.channel {
    xml.title(@digest.name)
    xml.description(@digest.name)
    xml.link(url_for(:only_path => false))
    for post in @posts
        xml.item do
            xml.title(post.title || '')
            xml.description(post.summary)
            xml.link(post.url)
            xml.source(post.feed.name)
            xml.guid(post.url)
            xml.pubDate(post.pub_date.to_s(:rfc822))
        end
     end
    }
}

To generate an rss feed(require rss) I use next code :

xml.source(post.feed.name)

and get:

<source>Cnn news</source>

But I want something like that:

<source url="http://news.cnn.com">Cnn news</source>

How can I add parameter url to xml source tag?

I’m not sure what library you’re using to do this but if you pass a hash to builder it’ll just add that as attributes of the node.

require 'builder'
 => true 
x = Builder::XmlMarkup.new(:target => $stdout, :indent => 1)
<inspect/>
 => #<IO:0x000000008822a0> 
x.source("CNN News", "url" => "http://www.cnn.com")
<source url="http://www.cnn.com">CNN News</source>
 => #<IO:<STDOUT>>
