Parse body of an email using Ruby on Rails

How do you parse out just the body of an email using Ruby on Rails? Below is what I have come up with. I have down to the subject with the body, but all I want is the body. I am trying to parse this without using TMail or email based libraries.

show

<p>Body: <%= @text.parse_body %></p>

controller

  def show
    @text = Text.find(params[:id])
  end

model

class Text < ActiveRecord::Base
  attr_accessible :email


  def text_input
      @raw_email = email.to_s
  end

  def parse_body
    @parse_email = @raw_email.match(/(\r\n\r\n[\W\w\S\s\D\d\b]*\r\n)/i)
    @parse_body = @parse_email.to_s.gsub(/<[\W\w\S\s\D\d\b]*?>/, "")
  end

result @parse_email

\r\n\r\n<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 3.2//EN\">\r\n<HTML>\r\n<HEAD>\r\n<META

Result of @parse_body

Body: Test for long subject Body

Result I am trying to get

Body

You should use a gem that does this for you, such as mail! You could do this:

mail = Mail.read(@raw_email)
mail.subject
mail.body

etc. Best to avoid writing your own parser in situations like this, if possible!

Note: I guess you say that you want to avoid mail libraries, but why? It will help a lot. This one is pure ruby, too.
