=head1 SYNOPSIS
+Create an L<HTML::Zoom> instance:
+
use HTML::Zoom;
my $root = HTML::Zoom
->from_html(<<MAIN);
<head>
<title>Default Title</title>
</head>
- <body>
+ <body bad_attr='junk'>
Default Content
</body>
</html>
MAIN
+Create a new attribute on the C<body> tag:
+
+ $root = $root
+ ->select('body')
+ ->set_attribute(class=>'main');
+
+Add a extra value to an existing attribute:
+
+ $root = $root
+ ->select('body')
+ ->add_to_attribute(class=>'one-column');
+
+Set the content of the C<title> tag:
+
+ $root = $root
+ ->select('title')
+ ->replace_content('Hello World');
+
+Set content from another L<HTML::Zoom> instance:
+
my $body = HTML::Zoom
->from_html(<<BODY);
<div id="stuff">
- <p>Stuff</p>
+ <p>Well Now</p>
+ <p id="p2">Is the Time</p>
</div>
BODY
- my $output = $root
- ->select('title')
- ->replace_content('Hello World')
- ->select('body')
- ->replace_content($body)
- ->to_html;
+ $root = $root
+ ->select('body')
+ ->replace_content($body);
+
+Set an attribute on multiple matches:
+
+ $root = $root
+ ->select('p')
+ ->set_attribute(class=>'para');
+
+Remove an attribute:
+
+ $root = $root
+ ->select('body')
+ ->remove_attribute('bad_attr');
will produce:
=begin testinfo
+ my $output = $root->to_html;
my $expect = <<HTML;
=end testinfo
<head>
<title>Hello World</title>
</head>
- <body><div id="stuff">
- <p>Stuff</p>
+ <body class="main one-column"><div id="stuff">
+ <p class="para">Well Now</p>
+ <p id="p2" class="para">Is the Time</p>
</div>
</body>
</html>
This class defines the following public API
-=head2 set_attribute
+=head2 set_attribute ( $attr=>value | {name=>$attr,value=>$value} )
- TBD
+Sets an attribute of a given name to a given value for all matching selections.
-=head2 add_attribute
+ $html_zoom
+ ->select('p')
+ ->set_attribute(class=>'paragraph')
+ ->select('div')
+ ->set_attribute(name=>'class', value=>'divider');
- TBD
-=head2 remove_attribute
+Overrides existing values, if such exist. When multiple L</set_attribute>
+calls are made against the same or overlapping selection sets, the final
+call wins.
- TBD
+=head2 add_to_attribute ( $attr=>value | {name=>$attr,value=>$value} )
+
+Adds a value to an existing attribute, or creates one if the attribute does not
+yet exist.
+
+ $html_zoom
+ ->select('p')
+ ->set_attribute(class=>'paragraph')
+ ->then
+ ->add_to_attribute(name=>'class', value=>'divider');
+
+Attributes with more than one value will have a dividing space.
+
+=head2 remove_attribute ( $attr | {name=>$attr} )
+
+Removes an attribute and all its values.
+
+ $html_zoom
+ ->select('p')
+ ->set_attribute(class=>'paragraph')
+ ->then
+ ->remove_attribute('class');
+
+Removes attributes from the original stream or events already added.
