425 L<DOM::Tiny> is a minimalistic and relaxed HTML/XML DOM parser with CSS
426 selector support based on L<Mojo::DOM>. It will even try to interpret broken
427 HTML and XML, so you should not use it for validation.
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.
487 my $trimmed = $dom->all_text;
488 my $untrimmed = $dom->all_text(0);
490 Extract text content from all descendant nodes of this element, smart
491 whitespace trimming is enabled by default.

504 Find all ancestor elements of this node matching the CSS selector and return a
505 L<DOM::Tiny::Collection> object containing these elements as L<DOM::Tiny>

508 # List tag names of ancestor elements
509 say $dom->ancestors->map('tag')->join("\n");
513 $dom = $dom->append('<p>I ♥ DOM::Tiny!</p>');
515 Append HTML/XML fragment to this node.
517 # "<div><h1>Test</h1><h2>123</h2></div>"
518 $dom->parse('<div><h1>Test</h1></div>')
519 ->at('h1')->append('<h2>123</h2>')->root;
