=head1 NAME
XML::Feed::Entry - Entry/item in a syndication feed
=head1 SYNOPSIS
## $feed is an XML::Feed object.
for my $entry ($feed->entries) {
print $entry->title, "\n", $entry->summary, "\n\n";
}
=head1 DESCRIPTION
I<XML::Feed::Entry> represents an entry/item in an L<XML::Feed> syndication
feed.
=head1 USAGE
=head2 XML::Feed::Entry->new($format)
Creates a new I<XML::Feed::Entry> object in the format I<$format>, which
should be either I<RSS> or I<Atom>.
=head2 $entry->convert($format)
Converts the I<XML::Feed::Entry> object into the I<$format> format, and
returns the new object.
=head2 $entry->title([ $title ])
The title of the entry.
=head2 $entry->base([ $base ])
The url base of the entry.
=head2 $entry->link([ $uri ])
The permalink of the entry, in most cases, except in cases where it points
instead to an offsite URI referenced in the entry.
=head2 $entry->content([ $content ])
An L<XML::Feed::Content> object representing the full entry body, or as
much as is available in the feed.
In RSS feeds, this method will look first for
L<http://purl.org/rss/1.0/modules/content/#encoded> and
L<http://www.w3.org/1999/xhtml#body> elements, then fall back to a
I<E<lt>descriptionE<gt>> element.
=head2 $entry->summary([ $summary ])
An L<XML::Feed::Content> object representing a short summary of the entry.
Possibly.
Since RSS feeds do not have the idea of a summary separate from the entry
body, this may not always be what you want. If the entry contains both a
I<E<lt>descriptionE<gt>> element B<and> another element typically used for
the full content of the entry--either I<http://www.w3.org/1999/xhtml/body>
or L<http://purl.org/rss/1.0/modules/content/#encoded>--we treat that as
the summary. Otherwise, we assume that there isn't a summary, and return
an L<XML::Feed::Content> object with an empty string in the I<body>.
=head2 $entry->category([ $category ])
The category in which the entry was posted.
Returns a list of categories if called in array context or the first
category if called in scalar context.
B<WARNING> It's possible this API might change to have an
I<add_category> instead.
=head2 $entry->tags([ $tag ])
A synonym (alias) for I<category>;
=head2 $entry->author([ $author ])
The name or email address of the person who posted the entry.
=head2 $entry->id([ $id ])
The unique ID of the entry.
=head2 $entry->issued([ $issued ])
A I<DateTime> object representing the date and time at which the entry
was posted.
If present, I<$issued> should be a I<DateTime> object.
=head2 $entry->modified([ $modified ])
A I<DateTime> object representing the last-modified date of the entry.
If present, I<$modified> should be a I<DateTime> object.
=head2 $entry->wrap
Take an entry in its native format and turn it into an I<XML::Feed::Entry> object.
=head2 $entry->unwrap
Take an I<XML::Feed::Entry> object and turn it into its native format.
=head1 AUTHOR & COPYRIGHT
Please see the I<XML::Feed> manpage for author, copyright, and license
information.
