NAME ^

HTML::Grabber

SYNOPSIS ^

    use HTML::Grabber;
    use LWP::Simple;

    my $dom = HTML::Grabber->new( html => get('http://twitter.com/ned0r') );

    $dom->find('.tweet-content')->each(sub {
        my $body = $_->find('.tweet-text')->text;
        my $when = $_->find('.js-tweet-timestamp')->attr('data-time');
        my $link = $_->find('.js-permalink')->attr('href');
        print "$body $when (link: $link)\n";
    });

DESCRIPTION ^

HTML::Grabber provides a jQuery style interface to HTML documents. This makes parsing and manipulating HTML documents trivially simple for those people familiar with http://jquery.com.

It uses XML::LibXML for DOM parsing/manipulation and HTML::Selector::XPath for converting CSS expressions into XPath.

SELECTORS ^

All selectors are CSS. They are internally converted to XPath using HTML::Selector::XPath. If some creative selector you're trying isn't working as expected, it may well be worth checking out the documentation for that module to see if it's supported.
