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.
