== Discussion
NASA's Astronomy Picture of the Day is a great source for nice astro
photos and various other information. But it isn't something I
remember to go see every day, so I'd like it to drop in my in-box or
an evernote notebook. But the feed does not include the image, for
some ungodly reason, so I'm adding a scraper to grab the nice info off
the page including the photo.

module Scrapers
module NasaApod
NASA_APOD_URL="http://asterisk.apod.com/library/APOD/APOD%20mirror/astropix.html"

def scrape(url=nil)
url ||= NASA_APOD_URL
apod = Hash.new
Mechanize.start do |m|
m.get url
# APOD has a funky entry page, but we want the actual page
prev = m.current_page.link_with(:text => '<').href
m.get prev
canonical = m.current_page.link_with(:text => '>' ).href
m.get canonical
m.current_page.tap do |page|
apod[:title] = page.title.strip
apod[:link] = page.uri.to_s
apod[:description] = (page/("body")).text
apod[:pubDate] = page.response['date'].to_s
apod[:guid] = page.uri.to_s
apod[:content_encoded] = (page/("body")).to_html
end
end
apod
end
end
