Ruby on rails 3.1 Incoming Email with th Mailman Gem

Question

I'm researching a solution for a client, where they receive orders through email. I understand that with the Mailman gem I can setup a server to fetch mail then parse attributes such as from, subject, body, etc. My question is what solution do i need to further analyze or scrape the body for attributes such as po number, quantity, price, department etc? I was thinking that if the email body had a very strict format I could do this, but it seems mailman matchers cannot get this specific. In addition I need to reply to each email to accept the order when a technician receives the order.

Answer 1

You could parse the body with nokogiri:

body_html = Nokogiri::HTML(your_body_variable_here)
body_html.css("#price").each do |p|
   # do whatever you want with each price
end

As for the reply to, you can loop trough the from variable of Mailman, ie:

message.from.each do |from|
   # do something
end

By the way, I did not test that code, just wrote it as I remember it to help you quickly...
