📋 SYNOPSIS

  use WWW::Search;
  my $oSearch = new WWW::Search('Ebay');
  my $sQuery = WWW::Search::escape_query("C-10 carded Yakface");

    { print $oResult->url, "\n"; }

📖 DESCRIPTION

This class is a Ebay specialization of WWW::Search. It handles making and interpreting Ebay searches http://www.ebay.com.

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 <TD> 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 in 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).
