This ruby script reads a KeePass XML export (v2) and inserts the entries into pass, the UNIX password manager. It will use a path starting with "KeePass/" so you can manually check the entries.

keepass2pass.rb

def find_path(entry)
  path = []
  until entry.parent.name == 'Root' do
    entry = entry.parent
    path.insert(0, entry.css('>Name').text)
  end
  path
end

def insert_entry(entry)
  attributes = Hash[entry.css('>String').map {|s| [s.css('Key').text, s.css('Value').text] }]
  return unless attributes.has_key?('Title') && attributes.has_key?('Password')
  path = find_path entry
  path[0] = 'KeePass'
  file = path.join('/') << '/' << attributes['Title']
  puts "Saving: #{file}"
  output = "#{attributes['Password']}"
  output << "\nUser: #{attributes['UserName']}" if attributes.has_key? 'UserName'
  attributes.delete 'Password'
  attributes.delete 'UserName'
  unless attributes.empty?
    output << "\n"
    attributes.each {|k,v| output << "\n#{k}: #{v}" }
  end
  ap `echo "#{output}" | pass insert -f -m #{file.gsub(' ', '\ ').gsub('&','-').gsub('\'','')}`
