You can use a tool like lxml that "understands" html (though in this case
you'd need a javascript parser on top of that) -- or hack something together
with string methods or regular expressions. For example:
import urllib2
import json
s = urllib2.urlopen("http://*********/goldencasket";).read()
s = s.partition("latestResults_productResults")[2].lstrip(" =")
s = s.partition(";")[0]
data = json.loads(s)
lotto = data["GoldLottoSaturday"]
print lotto["drawDayDateNumber"]
print map(int, lotto["primaryNumbers"])
print map(int, lotto["secondaryNumbers"])
While this is brittle I've found that doing it "right" is usually not
worthwhile as it won't survive the next website redesign eighter.
PS: <http://*********/goldencasket/results/download-results>
has links to zipped csv files with the results. Downloading, inflating and
reading these should be the simplest and best way to get your data.
