NAME

XML::Atom::Entry - Atom entry

SYNOPSIS

     use XML::Atom::Entry;
     my $entry = XML::Atom::Entry->new;
     $entry->title('My Post');
     $entry->content('The content of my post.');
     my $xml = $entry->as_xml;
     my $dc = XML::Atom::Namespace->new(dc => 'http://purl.org/dc/elements/1.1/');
     $entry->set($dc, 'subject', 'Food & Drink');
 
 

USAGE

XML::Atom::Entry->new([ $stream ])

Creates a new entry object, and if $stream is supplied, fills it with the data specified by $stream.

Automatically handles autodiscovery if $stream is a URI (see below).

Returns the new XML::Atom::Entry object. On failure, returns "undef".

$stream can be any one of the following:

•

Reference to a scalar

This is treated as the XML body of the entry.

•

Scalar

This is treated as the name of a file containing the entry XML.

•

Filehandle

This is treated as an open filehandle from which the entry XML can be read.

$entry->content([ $content ])

Returns the content of the entry. If $content is given, sets the content of the entry. Automatically handles all necessary escaping.

$entry->author([ $author ])

Returns an XML::Atom::Person object representing the author of the entry, or "undef" if there is no author information present.

If $author is supplied, it should be an XML::Atom::Person object representing the author. For example:

     my $author = XML::Atom::Person->new;
     $author->name('Foo Bar');
     $author->email('foo@bar.com');
     $entry->author($author);
 
 

$entry->link

If called in scalar context, returns an XML::Atom::Link object corresponding to the first <link> tag found in the entry.

If called in list context, returns a list of XML::Atom::Link objects corresponding to all of the <link> tags found in the entry.

$entry->add_link($link)

Adds the link $link, which must be an XML::Atom::Link object, to the entry as a new <link> tag. For example:

     my $link = XML::Atom::Link->new;
     $link->type('text/html');
     $link->rel('alternate');
     $link->href('http://www.example.com/2003/12/post.html');
     $entry->add_link($link);
 
 

$entry->get($ns, $element)

Given an XML::Atom::Namespace element $ns and an element name $element, retrieves the value for the element in that namespace.

This is useful for retrieving the value of elements not in the main Atom namespace, like categories. For example:

     my $dc = XML::Atom::Namespace->new(dc => 'http://purl.org/dc/elements/1.1/');
     my $subj = $entry->get($dc, 'subject');
 
 

$entry->getlist($ns, $element)

Just like $entry->get, but if there are multiple instances of the element $element in the namespace $ns, returns all of them. get will return only the first.
