I am looking for some direction for how to parse an email using nokogiri. Below is a sample email. I have reviewed this document http://nokogiri.org/tutorials/parsing_an_html_xml_document.html and hours of googleing. I am new at Ruby on Rails and am looking for a great example or detailed instructions. Thank you for your time.

    Nokogiri works great for parsing HTML, but what you have here is an email. Try using TMail to first get the HTML section from the email, then you can use Nokogiri to parse that. Extrapolating from the TMail docs, you could do something like:

      email = TMail::Mail.load('my_email.eml')
  html_doc = Nokogiri::HTML(email.body)
