NAME¶
WWW::Search::Yahoo - backend for searching www.yahoo.comSYNOPSIS¶
use WWW::Search; my $oSearch = new WWW::Search('Yahoo'); my $sQuery = WWW::Search::escape_query("sushi restaurant Columbus Ohio"); $oSearch->native_query($sQuery); while (my $oResult = $oSearch->next_result()) print $oResult->url, "\n";
DESCRIPTION¶
This class is a Yahoo specialization of WWW::Search. It handles making and interpreting Yahoo searches http://www.yahoo.com.This class exports no public interface; all interaction should be done through WWW::Search objects.
NOTES¶
The default search is: Yahoo's web-based index (not Directory).PRIVATE METHODS¶
If you just want to write Perl code to search Yahoo, you do NOT need to read any further here. Instead, just read the WWW::Search documentation.If you want to write a subclass of this module (e.g. create a backend for another branch of Yahoo) then please read about the private methods here:
gui_query¶
Yes, Virginia, we do try to emulate stupid-human queries.need_to_delay¶
This method tells the WWW::Search controller code whether we need to pause and give the yahoo.com servers a breather.user_agent_delay¶
This method tells the WWW::Search controller code how many seconds we should pause.preprocess_results_page¶
Clean up the Yahoo HTML before we attempt to parse it._result_list_tags¶
Returns a list, which will be passed as arguments to HTML::Element::look_down() in order to return a list of HTML::Element which contain the query results._result_list_items¶
Given an HTML::TreeBuilder tree, returns a list of HTML::Element, which contain the query results.parse_details¶
Given a (portion of an) HTML::TreeBuilder tree and a WWW::SearchResult object, parses one result out of the tree and populates the SearchResult._where_to_find_count¶
Returns a list, which will be passed as arguments to HTML::Element::look_down() in order to return an HTML::Element which contains the approximate result count._string_has_count¶
Given a string, returns the approximate result count if that string contains the approximate result count._a_is_next_link¶
Given an HTML::Element, returns true if it seems to contain the clickable "next page" widget.strip¶
