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 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 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).
