title: how to use the google maps api with greasemonkey to read a table of addresses and trace the route?
body: <p>There is a website which holds the buses routes for my city (<a href="https://secure.wikimedia.org/wikipedia/en/wiki/Porto_alegre" rel="nofollow noreferrer">Porto Alegre</a> - Brazil) in a table.</p>
  
  <p>ex: <a href="http://www.eptc.com.br/EPTC_Itinerarios/Cadastro.asp?Linha=255-0&amp;Tipo=I&amp;Veiculo=1&amp;Sentido=0&amp;Logradouro=0&amp;Action=Itiner%E1rio" rel="nofollow noreferrer">EPTC</a></p>
  
  <p>Using <a href="http://www.greasespot.net/" rel="nofollow noreferrer">Greasemonkey</a> to load de <a href="http://code.google.com/intl/pt-BR/apis/maps/documentation/javascript/" rel="nofollow noreferrer">Google Maps API</a>, id like to show a fixed map at the top right corner of the screeen.</p>
  
  <p>The script must read the street names from the table, strip de extra spaces (there are a lot of them), and draw the route in the right order.</p>
