WWW::Search::Yahoo - backend for searching www.yahoo.com
my $oSearch = new WWW::Search('Yahoo');
my $sQuery = WWW::Search::escape_query("sushi restaurant Columbus Ohio");
while (my $oResult = $oSearch->next_result())
print $oResult->url, "\n";
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.
The default search is: Yahoo's web-based index (not Directory).
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:
Yes, Virginia, we do try to emulate stupid-human queries.
This method tells the WWW::Search controller code whether we need to pause and give the yahoo.com servers a breather.
This method tells the WWW::Search controller code how many seconds we should pause.
Clean up the Yahoo HTML before we attempt to parse it.
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.
Given an HTML::TreeBuilder tree, returns a list of HTML::Element, which contain the query results.
Given a (portion of an) HTML::TreeBuilder tree and a WWW::SearchResult object, parses one result out of the tree and populates the SearchResult.
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.
Given a string, returns the approximate result count if that string contains the approximate result count.
Given an HTML::Element, returns true if it seems to contain the clickable "next page" widget.
Given a string, strips leading and trailing whitespace off of it.
To make new back-ends, see WWW::Search.
