       XML::Feed - Syndication feed parser and auto-discovery


           use XML::Feed;
           my $feed = XML::Feed->parse(URI->new(''))
               or die XML::Feed->errstr;
           print $feed->title, "\n";
           for my $entry ($feed->entries) {

           ## Find all of the syndication feeds on a given page, using
           ## auto-discovery.
           my @feeds = XML::Feed->find_feeds('');


       XML::Feed is a syndication feed parser for both RSS and Atom feeds. It also implements
       feed auto-discovery for finding feeds, given a URI.

       XML::Feed supports the following syndication feed formats:

       ·   RSS 0.91

       ·   RSS 1.0

       ·   RSS 2.0

       ·   Atom

       The goal of XML::Feed is to provide a unified API for parsing and using the various
       syndication formats. The different flavors of RSS and Atom handle data in different ways:
       date handling; summaries and content; escaping and quoting; etc. This module attempts to
       remove those differences by providing a wrapper around the formats and the classes
       implementing those formats (XML::RSS and XML::Atom::Feed). For example, dates are handled
       differently in each of the above formats. To provide a unified API for date handling,
       XML::Feed converts all date formats transparently into DateTime objects, which it then
       returns to the caller.


       Creates a new empty XML::Feed object using the format $format.

           $feed = XML::Feed->new('Atom');
           $feed = XML::Feed->new('RSS');
           $feed = XML::Feed->new('RSS', version => '0.91');

   XML::Feed->parse($stream, $format)
       Parses a syndication feed identified by $stream and returns an XML::Feed object. $stream
       can be any one of the following:

       ·   Scalar reference

           A reference to string containing the XML body of the feed.

       ·   Filehandle

           An open filehandle from which the feed XML will be read.

       ·   File name

           The name of a file containing the feed XML.

       ·   URI object

           A URI from which the feed XML will be retrieved.

       $format allows you to override format guessing.

       Gets a feed from a URI.

       Given a URI $uri, use auto-discovery to find all of the feeds linked from that page (using
       <link> tags).

       Returns a list of feed URIs.

       Given the xml of a feed return what format it is in, with "Atom" or "RSS" for all versions
       of RSS.  Note that you pass in a scalar ref to the xml string.

       Converts the XML::Feed object into the $format format, and returns the new object.

       Splices in all of the entries from the feed $other_feed into $feed, skipping posts that
       are already in $feed.

       Returns the format of the feed ("Atom", or some version of "RSS").

   $feed->title([ $title ])
       The title of the feed/channel.

   $feed->base([ $base ])
       The url base of the feed/channel.

   $feed->link([ $uri ])
       The permalink of the feed/channel.

   $feed->tagline([ $tagline ])
       The description or tagline of the feed/channel.

   $feed->description([ $description ])
       Alias for $feed->tagline.

   $feed->author([ $author ])
       The author of the feed/channel.

   $feed->language([ $language ])
       The language of the feed.

   $feed->copyright([ $copyright ])
       The copyright notice of the feed.

   $feed->modified([ $modified ])
       A DateTime object representing the last-modified date of the feed.

       If present, $modified should be a DateTime object.

   $feed->generator([ $generator ])
       The generator of the feed.

   $feed->self_link ([ $uri ])
       The Atom Self-link of the feed:


       A string.

       A list of the entries/items in the feed. Returns an array containing XML::Feed::Entry

       A synonym (alias) for <$feed->entries>.

       Adds an entry to the feed. $entry should be an XML::Feed::Entry object in the correct
       format for the feed.

       Returns an XML representation of the feed, in the format determined by the current format
       of the $feed object.

   $feed->first_link ([ $uri ])
       The Atom First-link for feed paging and archiving (RFC 5005).


   $feed->last_link ([ $uri ])
       The Atom Last-link for feed paging and archiving.

   $feed->next_link ([ $uri ])
       The Atom Next-link for feed paging and archiving.

   $feed->previous_link ([ $uri ])
       The Atom Previous-link for feed paging and archiving.

   $feed->current_link ([ $uri ])
       The Atom Current-link for feed paging and archiving.

   $feed->next_archive_link ([ $uri ])
       The Atom Next-link for feed paging and archiving.

   $feed->prev_archive_link ([ $uri ])
       The Atom Prev-Archive-link for feed paging and archiving.


           If you want to use another RSS parser class than XML::RSS (default), you can change
           the class by setting $PREFERRED_PARSER variable in the XML::Feed::Format::RSS package.

               $XML::Feed::Format::RSS::PREFERRED_PARSER = "XML::RSS::LibXML";

           Note: this will only work for parsing feeds, not creating feeds.

           Note: Only "XML::RSS::LibXML" version 0.3004 is known to work at the moment.

           Although the RSS specification states that there can be at most one enclosure per item
           some feeds break this rule.

           If this variable is set then "XML::Feed" captures all of them and makes them available
           as a list.

           Otherwise it returns the last enclosure parsed.

           Note: "XML::RSS" version 1.44 is needed for this to work.


       For reference, this cgi script will create valid, albeit nonsensical feeds (according to
       "" anyway) for Atom 1.0 and RSS 0.90, 0.91, 1.0 and 2.0.

           #!perl -w

           use strict;
           use CGI;
           use CGI::Carp qw(fatalsToBrowser);
           use DateTime;
           use XML::Feed;

           my $cgi  = CGI->new;
           my @args = ( $cgi->param('format') // "Atom" );
           push @args, ( version => $cgi->param('version') ) if $cgi->param('version');

           my $feed = XML::Feed->new(@args);
           $feed->title('Test Feed');
           $feed->self_link($cgi->url( -query => 1, -full => 1, -rewrite => 1) );

           my $entry = XML::Feed::Entry->new();
           $entry->title("Test entry");
           $entry->summary("Test summary");
           $entry->author(' (Testy McTesterson)');

           my $mime = ("Atom" eq $feed->format) ? "application/atom+xml" : "application/rss+xml";
           print $cgi->header($mime);
           print $feed->as_xml;
