423 L<DOM::Tiny> is a minimalistic and relaxed pure-perl HTML/XML DOM parser with
424 support for the L<HTML Living Standard|https://html.spec.whatwg.org/> and
425 L<CSS3 selectors|http://www.w3.org/TR/selectors/> based on L<Mojo::DOM>. It
426 will even try to interpret broken HTML and XML, so you should not use it for
429 =head1 NODES AND ELEMENTS
431 When we parse an HTML/XML fragment, it gets turned into a tree of nodes.
435 <head><title>Hello</title></head>
439 There are currently eight different kinds of nodes, C<cdata>, C<comment>,
440 C<doctype>, C<pi>, C<raw>, C<root>, C<tag> and C<text>. Elements are nodes of
452 While all node types are represented as L<DOM::Tiny> objects, some methods like
453 L</"attr"> and L</"namespace"> only apply to elements.
455 =head1 CASE-SENSITIVITY
457 L<DOM::Tiny> defaults to HTML semantics, that means all tags and attribute
458 names are lowercased and selectors need to be lowercase as well.
461 my $dom = DOM::Tiny->new('<P ID="greeting">Hi!</P>');
462 say $dom->at('p[id]')->text;
464 If XML processing instructions are found, the parser will automatically switch
465 into XML mode and everything becomes case-sensitive.
468 my $dom = DOM::Tiny->new('<?xml version="1.0"?><P ID="greeting">Hi!</P>');
469 say $dom->at('P[ID]')->text;
471 XML detection can also be disabled with the L</"xml"> method.
473 # Force XML semantics
474 my $dom = DOM::Tiny->new->xml(1)->parse('<P ID="greeting">Hi!</P>');
475 say $dom->at('P[ID]')->text;
477 # Force HTML semantics
478 my $dom = DOM::Tiny->new->xml(0)->parse('<P ID="greeting">Hi!</P>');
479 say $dom->at('p[id]')->text;
483 L<DOM::Tiny> implements the following methods.

488 my $dom = DOM::Tiny->new('<foo bar="baz">I ♥ DOM::Tiny!</foo>');
