evernote.rb

# This is a simple script to convert an XML file exported
# from Evernote into a bookmarks file that can be imported
# into Pinboard. In my case, all I cared about were notes
# that had a source-url, and all I'm retaining is the title
# and URL. I'm adding a fixed "evernote" tag for all notes.

require 'nokogiri'

def note_attributes(note)
  {
    href: note.at('source-url').text,
    tags: 'evernote',
    add_date: note.at('created').text
  }
rescue
  nil
end

def note_text(note)
  note.at('title').text
end

xml_doc = Nokogiri::XML(File.read('evernote.xml'))
html_doc = Nokogiri::HTML::Builder.new do |doc|
  doc.html {
    doc.body(:onload => 'some_func();') {
      doc.dl {
        xml_doc.css('note').each do |note|
          if note_attributes(note)
            doc.dt {
              doc.a(note_attributes(note)) {
                doc.text note_text(note)
              }
            }
          end
        end
      }
    }
  }
end

File.write('evernote.html', html_doc.to_html)

I had to manually manipulate the resulting HTML a bit to get this to work in Pinboard. I think the real key was removing the add_date attribute, as I think it was in the wrong format.
