# WWW::Search::Ebay - phpMan ## NAME [WWW::Search::Ebay] - backend for searching www.ebay.com ## SYNOPSIS use [WWW::Search]; my $oSearch = new [WWW::Search]('Ebay'); my $sQuery = [WWW::Search::escape_query]("C-10 carded Yakface"); $oSearch->native_query($sQuery); while (my $oResult = $oSearch->next_result()) { print $oResult->url, "\n"; } ## DESCRIPTION This class is a Ebay specialization of [WWW::Search]. It handles making and interpreting Ebay searches . This class exports no public interface; all interaction should be done through [WWW::Search] objects. ## NOTES The search is done against CURRENT running AUCTIONS only. (NOT completed auctions, NOT eBay Stores items, NOT Buy-It-Now only items.) (If you want to search completed auctions, use the [WWW::Search::Ebay::Completed] module.) (If you want to search eBay Stores, use the [WWW::Search::Ebay::Stores] module.) The query is applied to TITLES only. This module can return only the first 200 results matching your query. In the resulting [WWW::Search::Result] objects, the description() field consists of a human-readable combination (joined with semicolon-space) of the Item Number; number of bids; and high bid amount (or starting bid amount). In the resulting [WWW::Search::Result] objects, the end_date() field contains a human-readable DTG of when the auction is scheduled to end (in the form "YYYY-MM-DD HH:MM TZ"). If environment variable TZ is set, the time will be converted to that timezone; otherwise the time will be left in ebay.com's default timezone (US/Pacific). In the resulting [WWW::Search::Result] objects, the bid_count() field contains the number of bids as an integer. In the resulting [WWW::Search::Result] objects, the bid_amount() field is a string containing the high bid or starting bid as a human-readable monetary value in seller-native units, e.g. "$14.95" or "GBP 6.00". In the resulting [WWW::Search::Result] objects, the sold() field will be non-zero if the item has already sold. (Only if you're using [WWW::Search::Ebay::Completed]) After a successful search, your search object will contain an element named 'categories' which will be a reference to an array of hashes containing names and IDs of categories and nested subcategories, and the count of items matching your query in each category and subcategory. (Special thanks to Nick Lokkju for this code!) For example: $oSearch->{categories} = [ { 'ID' => '1', 'Count' => 19, 'Name' => 'Collectibles', 'Subcategory' => [ { 'ID' => '13877', 'Count' => 11, 'Name' => 'Historical Memorabilia' }, { 'ID' => '11450', 'Count' => 1, 'Name' => 'Clothing, Shoes & Accessories' }, ] }, { 'ID' => '281', 'Count' => 1, 'Name' => 'Jewelry & Watches', } ]; If your query string happens to be an eBay item number, (i.e. if ebay.com redirects the query to an auction page), you will get back one [WWW::Search::Result] without bid or price information. ## OPTIONS Limit search by price range Contributed by Brian Wilson: $oSearch->native_query($sQuery, { _mPrRngCbx=>'1', _udlo=>$minPrice, _udhi=>$maxPrice, } ); ## PUBLIC METHODS OF NOTE user_agent_delay Introduce a few-seconds delay to avoid overwhelming the server. need_to_delay Controls whether we do the delay or not. preprocess_results_page Grabs the eBay Official Time so that when we parse the DTG from the HTML, we can convert / return exactly what eBay means for each one. result_as_HTML Given a [WWW::SearchResult] object representing an auction, formats it human-readably with HTML. An optional second argument is the date format, a string as specified for [Date::Manip::UnixDate]. Default is '%Y-%m-%d %H:%M:%S' my $sHTML = $oSearch->result_as_HTML($oSearchResult, '%H:%M %b %E'); METHODS TO BE OVERRIDDEN IN SUBCLASSING You only need to read about these if you are subclassing this module (i.e. making a backend for another flavor of eBay search). _get_result_count_elements Given an [HTML::TreeBuilder] object, return a list of [HTML::Element] objects therein which could possibly contain the approximate result count verbiage. _get_itemtitle_tds Given an [HTML::TreeBuilder] object, return a list of [HTML::Element] objects therein representing elements which could possibly contain the HTML for result title and hotlink. _parse_category_list Parses the Category list from the left side of the results page. So far, this method can handle every type of eBay search currently implemented. If you find that it doesn't suit your needs, please contact the author because it's probably just a tiny tweak that's needed. _process_date_abbrevs Given a date string, converts common abbreviations to their full words (so that the string can be unambiguously parsed by [Date::Manip]). For example, in the default English, 'd' becomes 'days'. _next_text The text of the "Next" button, localized for a specific type of eBay backend. whitespace_pattern Return a qr// pattern to match whitespace your webpage's language. _currency_pattern Return a qr// pattern to match mentions of money in your webpage's language. Include the digits in the pattern. _title_pattern Return a qr// pattern to match the webpage title in your webpage's language. Add grouping parenthesis so that $1 becomes the auction title, $2 becomes the eBay item number, and $3 becomes the end date. _result_count_pattern Return a qr// pattern to match the result count in your webpage's language. Include parentheses so that $1 becomes the number (with commas is OK). ## SEE ALSO To make new back-ends, see [WWW::Search]. ## BUGS Please tell the author if you find any! ## AUTHOR Martin 'Kingpin' Thurn, "mthurn at cpan.org", <>.
