Also, if you want to process the HTML of that page, you might wish to 
get the HTML into an SXML/xexp format like this does:

#lang racket/base
(require net/url
          (planet neil/html-parsing))
(call/input-url (string->url "http://www.google.com/")

This SXML can be processed using tools like SXPath and "sxml-match".

This SXML can also be processed using low-level Racket list-processing 
procedures like "car", "cdr", and "pair?" and recursive procedures.
