SYNOPSIS

9         use Mojo::DOM;
10
11         # Parse
12         my $dom = Mojo::DOM->new('<div><p id="a">Test</p><p id="b">123</p></div>');
13
14         # Find
15         say $dom->at('#b')->text;
16         say $dom->find('p')->map('text')->join("\n");
17         say $dom->find('[id]')->map(attr => 'id')->join("\n");
18
19         # Iterate
20         $dom->find('p[id]')->reverse->each(sub { say $_->{id} });
21
22         # Loop
23         for my $e ($dom->find('p[id]')->each) {
24           say $e->{id}, ':', $e->text;
25         }
26
27         # Modify
28         $dom->find('div p')->last->append('<p id="c">456</p>');
29         $dom->at('#c')->prepend($dom->new_tag('p', id => 'd', '789'));
30         $dom->find(':not(p)')->map('strip');
31
32         # Render
33         say "$dom";

DESCRIPTION

36       Mojo::DOM is a minimalistic and relaxed HTML/XML DOM parser with CSS
37       selector support. It will even try to interpret broken HTML and XML, so
38       you should not use it for validation.
39

NODES AND ELEMENTS

41       When we parse an HTML/XML fragment, it gets turned into a tree of
42       nodes.
43
44         <!DOCTYPE html>
45         <html>
46           <head><title>Hello</title></head>
47           <body>World!</body>
48         </html>
49
50       There are currently eight different kinds of nodes, "cdata", "comment",
51       "doctype", "pi", "raw", "root", "tag" and "text". Elements are nodes of
52       the type "tag".
53
54         root
55         |- doctype (html)
56         +- tag (html)
57            |- tag (head)
58            |  +- tag (title)
59            |     +- raw (Hello)
60            +- tag (body)
61               +- text (World!)
62
63       While all node types are represented as Mojo::DOM objects, some methods
64       like "attr" and "namespace" only apply to elements.
65

CASE-SENSITIVITY

67       Mojo::DOM defaults to HTML semantics, that means all tags and attribute
68       names are lowercased and selectors need to be lowercase as well.
69
70         # HTML semantics
71         my $dom = Mojo::DOM->new('<P ID="greeting">Hi!</P>');
72         say $dom->at('p[id]')->text;
73
74       If an XML declaration is found, the parser will automatically switch
75       into XML mode and everything becomes case-sensitive.
76
77         # XML semantics
78         my $dom = Mojo::DOM->new('<?xml version="1.0"?><P ID="greeting">Hi!</P>');
79         say $dom->at('P[ID]')->text;
80
81       HTML or XML semantics can also be forced with the "xml" method.
82
83         # Force HTML semantics
84         my $dom = Mojo::DOM->new->xml(0)->parse('<P ID="greeting">Hi!</P>');
85         say $dom->at('p[id]')->text;
86
87         # Force XML semantics
88         my $dom = Mojo::DOM->new->xml(1)->parse('<P ID="greeting">Hi!</P>');
89         say $dom->at('P[ID]')->text;
90

METHODS

92       Mojo::DOM implements the following methods.
93
94   all_text
95         my $text = $dom->all_text;
96
97       Extract text content from all descendant nodes of this element.
98
99         # "foo\nbarbaz\n"
100         $dom->parse("<div>foo\n<p>bar</p>baz\n</div>")->at('div')->all_text;
101
102   ancestors
103         my $collection = $dom->ancestors;
104         my $collection = $dom->ancestors('div ~ p');
105
106       Find all ancestor elements of this node matching the CSS selector and
107       return a Mojo::Collection object containing these elements as Mojo::DOM
108       objects.  All selectors from "SELECTORS" in Mojo::DOM::CSS are
109       supported.
110
111         # List tag names of ancestor elements
112         say $dom->ancestors->map('tag')->join("\n");
113
114   append
115         $dom = $dom->append('<p>I ♥ Mojolicious!</p>');
116         $dom = $dom->append(Mojo::DOM->new);
117
118       Append HTML/XML fragment to this node (for all node types other than
119       "root").
120
121         # "<div><h1>Test</h1><h2>123</h2></div>"
122         $dom->parse('<div><h1>Test</h1></div>')
123           ->at('h1')->append('<h2>123</h2>')->root;
124
125         # "<p>Test 123</p>"
126         $dom->parse('<p>Test</p>')->at('p')
127           ->child_nodes->first->append(' 123')->root;
128
129   append_content
130         $dom = $dom->append_content('<p>I ♥ Mojolicious!</p>');
131         $dom = $dom->append_content(Mojo::DOM->new);
132
133       Append HTML/XML fragment (for "root" and "tag" nodes) or raw content to
134       this node's content.
135
136         # "<div><h1>Test123</h1></div>"
137         $dom->parse('<div><h1>Test</h1></div>')
138           ->at('h1')->append_content('123')->root;
139
140         # "<!-- Test 123 --><br>"
141         $dom->parse('<!-- Test --><br>')
142           ->child_nodes->first->append_content('123 ')->root;
143
144         # "<p>Test<i>123</i></p>"
145         $dom->parse('<p>Test</p>')->at('p')->append_content('<i>123</i>')->root;
146
147   at
148         my $result = $dom->at('div ~ p');
149         my $result = $dom->at('svg|line', svg => 'http://www.w3.org/2000/svg');
150
151       Find first descendant element of this element matching the CSS selector
152       and return it as a Mojo::DOM object, or "undef" if none could be found.
153       All selectors from "SELECTORS" in Mojo::DOM::CSS are supported.
154
155         # Find first element with "svg" namespace definition
156         my $namespace = $dom->at('[xmlns\:svg]')->{'xmlns:svg'};
157
158       Trailing key/value pairs can be used to declare xml namespace aliases.
159
160         # "<rect />"
161         $dom->parse('<svg xmlns="http://www.w3.org/2000/svg"><rect /></svg>')

169
170       This element's attributes.

202       objects.  All selectors from "SELECTORS" in Mojo::DOM::CSS are
203       supported.
204
