NAME

WWW::Mixi::Scraper - yet another mixi scraper

SYNOPSIS

    use WWW::Mixi::Scraper;
    my $mixi = WWW::Mixi::Scraper->new(
      email => 'foo@bar.com', password => 'password',
      mode  => 'TEXT'
    );

    my @list = $mixi->parse('http://mixi.jp/new_friend_diary.pl');
    my @list = $mixi->new_friend_diary->parse;

    my @list = $mixi->parse('http://mixi.jp/new_bbs.pl?page=2');
    my @list = $mixi->new_bbs->parse( page => 2 );

    my $diary = $mixi->parse('/view_diary.pl?id=0&owner_id=0');
    my $diary = $mixi->view_diary->parse( id => 0, owner_id => 0 );

    my @comments = @{ $diary->{comments} };

    # for testing
    my $html = read_file('/some/where/mixi.html');
    my $diary = $mixi->parse('/view_diary.pl', html => $html );
    my $diary = $mixi->view_diary->parse( html => $html );

DESCRIPTION

This is yet another 'mixi' (the largest SNS in Japan) scraper, powered by Web::Scraper. Though APIs are different and incompatible with precedent WWW::Mixi, I'm loosely trying to keep correspondent return values look similar as of writing this (this may change in the future).

WWW::Mixi::Scraper is also pluggable, so if you want to scrape something it can't handle now, add your WWW::Mixi::Scraper::Plugin::<PLfileBasenameInCamel>, and it'll work for you.

DIFFERENCES BETWEEN TWO

WWW::Mixi has much longer history and is full-stack. The data it returns tended to be more complete, fine-tuned, and raw in many ways (including encoding). However, it tended to suffer from minor html changes as it heavily relies on regexes, and as of writing this (July 2008), it's been broken for months due to a major cosmetic change of mixi in October, 2007.

In contrast, WWW::Mixi::Scraper hopefully tends to survive minor html changes as it relies on XPath/CSS selectors. And basically it uses decoded perl strings, not octets. It's smaller, and pluggable. However, its data is more or less pre-processed and tends to lose some aspects such as proper line breaks. Also, it may be easier to be polluted with garbages. And it may be harder to understand and maintain scraping rules.

Anyway, though a bit limited, ::Scraper is the only practical option right now.

IF YOU WANT MORE

If you want more features, please send me a patch, or a pull request from your github fork. Just telling me where you want to scrape would be ok but it may take a longer time to implement especially when it's new or less popular and I don't have enough samples.

ON Plagger::Plugin::CustomFeed::MixiScraper

Usually you want to use this with Plagger, but unfortunately, the current CPAN version of Plagger (0.7.17) doesn't have the above plugin. You can always get the latest version of the plugin from the Plagger's official repository at github (http://github.com/miyagawa/plagger/tree/master). See Plagger's official site (http://plagger.org/) for instructions to update your Plagger and install extra plugins.

METHODS

new

creates an object. You can pass an optional hash. Important keys are:

email, password

the ones you use to login.

mode

WWW::Mixi::Scraper has changed its policy since 0.08, and now it returns raw HTML for some of the longer texts like user's profile or diary body by default. However, this may cause various kind of problems. If you don't like HTML output, set this 'mode' option to 'TEXT', then it returns pre-processed texts as before.

would be passed to WWW::Mechanize. If your cookie_jar has valid cookies for mixi, you don't need to write your email/password in your scripts.

Other options would be passed to Mech, too.

parse

takes a uri and returns scraped data, which is mainly an array, sometimes a hash reference, or possibly something else, according to the plugin that does actual scraping. You can pass an optional hash, which eventually override query parameters of the uri. An exception is 'html', which wouldn't go into the uri but provide raw html string to the scraper (mainly to test).

TO DO

More scraper plugins, various levels of caching, password obfuscation, some getters of minor information such as pager, counter, and image/thumbnail sources, and maybe more docs?

Anyway, as this is a 'scraper', I don't include 'post' related methods here. If you insist, use WWW::Mechanize object hidden in the stash, or WWW::Mixi.
