NAME

WWW::Search::YahooNews - backend for searching Yahoo News

SYNOPSIS

use WWW::Search; $query = "Bob Hope"; $search = new WWW::Search('YahooNews'); $search->native_query(WWW::Search::escape_query($query)); $search->maximum_to_retrieve(100); while (my $result = $search->next_result()) {

$url = $result->url; $title = $result->title; $desc = $result->description;

print "<a href=$url>$title</a><br>$desc<p>\n"; }

DESCRIPTION

This class is a Yahoo specialization of WWW::Search. It handles making and interpreting Yahoo News Searches. Yahoo allows searching a wide variety of news sources like SEC and PRWire to name a few. http://www.search.news.yahoo.com.

HOW DOES IT WORK?

native_setup_search is called (from WWW::Search::setup_search) before we do anything. It initializes our private variables (which all begin with underscore) and sets up a URL to the first results page in {_next_url}.

native_retrieve_some is called (from WWW::Search::retrieve_some) whenever more hits are needed. It calls WWW::Search::http_request to fetch the page specified by {_next_url}. It then parses this page, appending any search hits it finds to {cache}. If it finds a ``next'' button in the text, it sets {_next_url} to point to the page for the next set of results, otherwise it sets it to undef to indicate we''re done.
