7 | DOM::Tiny - Minimalistic HTML/XML DOM parser with CSS selectors |
8 | |
9 | =head1 SYNOPSIS |
10 | |
11 | use DOM::Tiny; |
12 | |
13 | # Parse |
14 | my $dom = DOM::Tiny->new('<div><p id="a">Test</p><p id="b">123</p></div>'); |
15 | |
16 | # Find |
17 | say $dom->at('#b')->text; |
18 | say $dom->find('p')->map('text')->join("\n"); |
19 | say $dom->find('[id]')->map(attr => 'id')->join("\n"); |
20 | |
21 | # Iterate |
22 | $dom->find('p[id]')->reverse->each(sub { say $_->{id} }); |
23 | |
24 | # Loop |
25 | for my $e ($dom->find('p[id]')->each) { |
26 | say $e->{id}, ':', $e->text; |
27 | } |
28 | |
29 | # Modify |
30 | $dom->find('div p')->last->append('<p id="c">456</p>'); |
31 | $dom->find(':not(p)')->map('strip'); |
32 | |
33 | # Render |
34 | say "$dom"; |

36 | =head1 DESCRIPTION |
37 | |
38 | L<DOM::Tiny> is a minimalistic and relaxed HTML/XML DOM parser with CSS |
39 | selector support based on L<Mojo::DOM>. It will even try to interpret broken |
40 | HTML and XML, so you should not use it for validation. |
41 | |
42 | =head1 NODES AND ELEMENTS |
43 | |
44 | When we parse an HTML/XML fragment, it gets turned into a tree of nodes. |
45 | |
46 | <!DOCTYPE html> |
47 | <html> |
48 | <head><title>Hello</title></head> |
49 | <body>World!</body> |
50 | </html> |
51 | |
52 | There are currently eight different kinds of nodes, C<cdata>, C<comment>, |
53 | C<doctype>, C<pi>, C<raw>, C<root>, C<tag> and C<text>. Elements are nodes of |
54 | the type C<tag>. |
55 | |
56 | root |
57 | |- doctype (html) |
58 | +- tag (html) |
59 | |- tag (head) |
60 | | +- tag (title) |
61 | | +- raw (Hello) |
62 | +- tag (body) |
63 | +- text (World!) |
64 | |
65 | While all node types are represented as L<DOM::Tiny> objects, some methods like |
66 | L</"attr"> and L</"namespace"> only apply to elements. |
67 | |
68 | =head1 CASE-SENSITIVITY |
69 | |
70 | L<DOM::Tiny> defaults to HTML semantics, that means all tags and attribute |
71 | names are lowercased and selectors need to be lowercase as well. |
72 | |
73 | # HTML semantics |
74 | my $dom = DOM::Tiny->new('<P ID="greeting">Hi!</P>'); |
75 | say $dom->at('p[id]')->text; |
76 | |
77 | If XML processing instructions are found, the parser will automatically switch |
78 | into XML mode and everything becomes case-sensitive. |
79 | |
80 | # XML semantics |
81 | my $dom = DOM::Tiny->new('<?xml version="1.0"?><P ID="greeting">Hi!</P>'); |
82 | say $dom->at('P[ID]')->text; |
83 | |
84 | XML detection can also be disabled with the L</"xml"> method. |
85 | |
86 | # Force XML semantics |
87 | my $dom = DOM::Tiny->new->xml(1)->parse('<P ID="greeting">Hi!</P>'); |
88 | say $dom->at('P[ID]')->text; |
89 | |
90 | # Force HTML semantics |
91 | my $dom = DOM::Tiny->new->xml(0)->parse('<P ID="greeting">Hi!</P>'); |
92 | say $dom->at('p[id]')->text; |
93 | |
94 | =head1 METHODS |
