doc = Hpricot::XML(open('http://www.cnn.com/.element/ssi/www/auto/2.0/video/xml/most_popular.xml'))
(doc/:cnn_video/:video).each do |status|
  ['tease_txt'].each do |el|
    puts "#{status.at(el).inner_text}"
  end
end

doc.search("*") do |element|
    element.swap element.content if element.kind_of? Hpricot::CData
end

use element.inner_text instead of #inner_html and it removes them for you
