Extracting image url from podcast

[joshr]

Hello all, and thanks for the great library. I'm working on an app
that needs to parse podcast feeds and I'm having some trouble reading
the image url. I'm unsure of the format of the name that gets passed
into the element method to define this on my parser classes. Here is
an example feed with some of the guts chopped out:

<channel>
<title>IT Conversations</title>
<image>
<url>http://assets.conversationsnetwork.org/channels/
ITConversations/itc-300x300.jpg</url>
<title>IT Conversations</title>
<link>http://itc.conversationsnetwork.org</link>
</image>
</channel>

I expected it to be something along these lines but I was just
guessing:

class Feedzirra::Parser::Atom
element "image > url", :as => :image_url
end

Any pointers would be appreciated.
