=head1 NAME
-DOM::Tiny - Minimalistic HTML/XML DOM parser with CSS selectors
-
-=head1 SYNOPSIS
-
- use DOM::Tiny;
-
- # Parse
- my $dom = DOM::Tiny->new('<div><p id="a">Test</p><p id="b">123</p></div>');
-
- # Find
- say $dom->at('#b')->text;
- say $dom->find('p')->map('text')->join("\n");
- say $dom->find('[id]')->map(attr => 'id')->join("\n");
-
- # Iterate
- $dom->find('p[id]')->reverse->each(sub { say $_->{id} });
-
- # Loop
- for my $e ($dom->find('p[id]')->each) {
- say $e->{id}, ':', $e->text;
- }
-
- # Modify
- $dom->find('div p')->last->append('<p id="c">456</p>');
- $dom->find(':not(p)')->map('strip');
-
- # Render
- say "$dom";
-
-=head1 DESCRIPTION
-
-L<DOM::Tiny> is a minimalistic and relaxed pure-perl HTML/XML DOM parser based
-on L<Mojo::DOM>. It supports the L<HTML Living Standard|https://html.spec.whatwg.org/>
-and L<Extensible Markup Language (XML) 1.0|http://www.w3.org/TR/xml/>, and
-matching based on L<CSS3 selectors|http://www.w3.org/TR/selectors/>. It will
-even try to interpret broken HTML and XML, so you should not use it for
-validation.
-
-=head1 NODES AND ELEMENTS
-
-When we parse an HTML/XML fragment, it gets turned into a tree of nodes.
-
- <!DOCTYPE html>
- <html>
- <head><title>Hello</title></head>
- <body>World!</body>
- </html>
-
-There are currently eight different kinds of nodes, C<cdata>, C<comment>,
-C<doctype>, C<pi>, C<raw>, C<root>, C<tag> and C<text>. Elements are nodes of
-the type C<tag>.
-
- root
- |- doctype (html)
- +- tag (html)
- |- tag (head)
- | +- tag (title)
- | +- raw (Hello)
- +- tag (body)
- +- text (World!)
-
-While all node types are represented as L<DOM::Tiny> objects, some methods like
-L</"attr"> and L</"namespace"> only apply to elements.
-
-=head1 CASE-SENSITIVITY
-
-L<DOM::Tiny> defaults to HTML semantics, that means all tags and attribute
-names are lowercased and selectors need to be lowercase as well.
-
- # HTML semantics
- my $dom = DOM::Tiny->new('<P ID="greeting">Hi!</P>');
- say $dom->at('p[id]')->text;
-
-If XML processing instructions are found, the parser will automatically switch
-into XML mode and everything becomes case-sensitive.
-
- # XML semantics
- my $dom = DOM::Tiny->new('<?xml version="1.0"?><P ID="greeting">Hi!</P>');
- say $dom->at('P[ID]')->text;
-
-XML detection can also be disabled with the L</"xml"> method.
-
- # Force XML semantics
- my $dom = DOM::Tiny->new->xml(1)->parse('<P ID="greeting">Hi!</P>');
- say $dom->at('P[ID]')->text;
-
- # Force HTML semantics
- my $dom = DOM::Tiny->new->xml(0)->parse('<P ID="greeting">Hi!</P>');
- say $dom->at('p[id]')->text;
-
-=head1 SELECTORS
-
-L<DOM::Tiny> uses a CSS selector engine based on L<Mojo::DOM::CSS>. All CSS
-selectors that make sense for a standalone parser are supported.
-
-=head2 *
-
-Any element.
-
- my $all = $dom->find('*');
-
-=head2 E
-
-An element of type C<E>.
-
- my $title = $dom->at('title');
-
-=head2 E[foo]
-
-An C<E> element with a C<foo> attribute.
-
- my $links = $dom->find('a[href]');
-
-=head2 E[foo="bar"]
-
-An C<E> element whose C<foo> attribute value is exactly equal to C<bar>.
-
- my $case_sensitive = $dom->find('input[type="hidden"]');

-
-=head2 E[foo="bar" i]
-
-An C<E> element whose C<foo> attribute value is exactly equal to any
-(ASCII-range) case-permutation of C<bar>. Note that this selector is
-EXPERIMENTAL and might change without warning!
-
- my $case_insensitive = $dom->find('input[type="hidden" i]');
- my $case_insensitive = $dom->find('input[type=hidden i]');
- my $case_insensitive = $dom->find('input[class~="foo" i]');
-
-This selector is part of
-L<Selectors Level 4|http://dev.w3.org/csswg/selectors-4>, which is still a work
-in progress.
-
-=head2 E[foo~="bar"]
-
-An C<E> element whose C<foo> attribute value is a list of whitespace-separated
-values, one of which is exactly equal to C<bar>.

- my $foo = $dom->find('input[class~=foo]');
-
-=head2 E[foo^="bar"]
-
-An C<E> element whose C<foo> attribute value begins exactly with the string
-C<bar>.

- my $begins_with = $dom->find('input[name^=f]');
-
-=head2 E[foo$="bar"]
-
-An C<E> element whose C<foo> attribute value ends exactly with the string
-C<bar>.
-
- my $ends_with = $dom->find('input[name$="o"]');
- my $ends_with = $dom->find('input[name$=o]');
-
-=head2 E[foo*="bar"]
-
-An C<E> element whose C<foo> attribute value contains the substring C<bar>.
