I don't know of any 1:1 relationship that could be assumed in general terms where a HTML web page is translated into a hash table. There is no implicit set of rules that we could use to take a stab at what you're trying to accomplish. That being the case, we really don't have enough information to be able to provide anything more than generic help.

For web-scraping, WWW::Mechanize is convenient. HTML::TreeBuilder is a pretty good generalized HTML parser.
