Answer 1

Here is what I did for replacing images src attributes:

      doc = Nokogiri::HTML(html)
       doc.xpath("//img").each do |img|
         img.attributes["src"].value = Absolute_asset_path(img.attributes["src"].value)

      doc.to_html                  // simply use .to_html to re-convert to html
