NAME

Mojo::DOM - Minimalistic XML DOM Parser With CSS3 Selectors

SYNOPSIS

    use Mojo::DOM;

    # Parse
    my $dom = Mojo::DOM->new;
    $dom->parse('<div><div id="a">A</div><div id="b">B</div></div>');

    # Find
    my $b = $dom->at('#b');
    print $b->text;

    # Iterate
    $dom->find('div[id]')->each(sub { print shift->text });

DESCRIPTION

Mojo::DOM is a minimalistic and very relaxed XML DOM parser with support for CSS3 selectors. Note that this module is EXPERIMENTAL and might change without warning!

SELECTORS

These CSS3 selectors are currently implemented.

*

Any element.

E
    my $title = $dom->at('title');

An element of type E.

E[foo]
    my $links = $dom->find('a[href]');

An E element with a foo attribute.

E[foo="bar"]
    my $fields = $dom->find('input[name="foo"]');

An E element whose foo attribute value is exactly equal to bar.

E[foo^="bar"]
    my $fields = $dom->find('input[name^="f"]');

An E element whose foo attribute value begins exactly with the string bar.

E[foo$="bar"]
    my $fields = $dom->find('input[name$="o"]');

An E element whose foo attribute value ends exactly with the string bar.

E:root
    my $root = $dom->at(':root');

An E element, root of the document.

E F
    my $headlines = $dom->find('div h1');

An F element descendant of an E element.

E > F
    my $headlines = $dom->find('html > body > div > h1');

An F element child of an E element.
