HTML::Parser walkthrough?

[Ben Ostrowsky]

I'm trying to build a script that will go to a NOAA web page, find the 
current temperature, and return just that information.

If the first TABLE in the document is TABLE[0], then the data I want is, I 
think, at:

HTML > BODY > TABLE[3] > TR[7] > TD[1]

But how can I use Perl to get the contents of that TD?  I don't understand 
the HTML::Parser manpage.
