43 XML::Atom::Entry - Atom entry
48 my $entry = XML::Atom::Entry->new;
49 $entry->title('My Post');
50 $entry->content('The content of my post.');
51 my $xml = $entry->as_xml;
52 my $dc = XML::Atom::Namespace->new(dc => 'http://purl.org/dc/elements/1.1/');
53 $entry->set($dc, 'subject', 'Food & Drink');
57 =head2 XML::Atom::Entry->new([ $stream ])
59 Creates a new entry object, and if I<$stream> is supplied, fills it with the
60 data specified by I<$stream>.
62 Automatically handles autodiscovery if I<$stream> is a URI (see below).
64 Returns the new I<XML::Atom::Entry> object. On failure, returns C<undef>.
66 I<$stream> can be any one of the following:
70 =item * Reference to a scalar
72 This is treated as the XML body of the entry.
76 This is treated as the name of a file containing the entry XML.
80 This is treated as an open filehandle from which the entry XML can be read.
84 =head2 $entry->content([ $content ])
86 Returns the content of the entry. If I<$content> is given, sets the content
87 of the entry. Automatically handles all necessary escaping.
89 =head2 $entry->author([ $author ])
91 Returns an I<XML::Atom::Person> object representing the author of the entry,
92 or C<undef> if there is no author information present.
94 If I<$author> is supplied, it should be an I<XML::Atom::Person> object
95 representing the author. For example:
97 my $author = XML::Atom::Person->new;
98 $author->name('Foo Bar');
99 $author->email('foo@bar.com');
100 $entry->author($author);
104 If called in scalar context, returns an I<XML::Atom::Link> object
105 corresponding to the first I<E<lt>linkE<gt>> tag found in the entry.
107 If called in list context, returns a list of I<XML::Atom::Link> objects
108 corresponding to all of the I<E<lt>linkE<gt>> tags found in the entry.
110 =head2 $entry->add_link($link)
112 Adds the link I<$link>, which must be an I<XML::Atom::Link> object, to
113 the entry as a new I<E<lt>linkE<gt>> tag. For example:
115 my $link = XML::Atom::Link->new;
116 $link->type('text/html');
117 $link->rel('alternate');
118 $link->href('http://www.example.com/2003/12/post.html');
119 $entry->add_link($link);
121 =head2 $entry->get($ns, $element)
123 Given an I<XML::Atom::Namespace> element I<$ns> and an element name
124 I<$element>, retrieves the value for the element in that namespace.
126 This is useful for retrieving the value of elements not in the main Atom
127 namespace, like categories. For example:
129 my $dc = XML::Atom::Namespace->new(dc => 'http://purl.org/dc/elements/1.1/');
130 my $subj = $entry->get($dc, 'subject');
132 =head2 $entry->getlist($ns, $element)
134 Just like I<$entry-E<gt>get>, but if there are multiple instances of the
135 element I<$element> in the namespace I<$ns>, returns all of them. I<get>
136 will return only the first.
