question about urllib and parsing a page

[nephish at xit.net]

hey there,
i am using beautiful soup to parse a few pages (screen scraping)
easy stuff.
the issue i am having is with one particular web page that uses a
javascript to display some numbers in tables.

now if i open the file in mozilla and "save as" i get the numbers in
the source. cool. but i click on the "view source" or download the url
with urlretrieve, i get the source, but not the numbers.

is there a way around this ?

thanks
