NAME

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

SYNOPSIS

    use XML::Feed;
    my $feed = XML::Feed->parse(URI->new('http://example.com/atom.xml'))
        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('http://example.com/');

DESCRIPTION

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.

USAGE

XML::Feed->parse($stream)

Parses a syndication feed identified by $stream. $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.

XML::Feed->find_feeds($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.

$feed->format

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

$feed->title

The title of the feed/channel.

$feed->link

The permalink of the feed/channel.

$feed->tagline

The description or tagline of the feed/channel.

$feed->description

Alias for $feed->tagline.

$feed->language

The language of the feed.

$feed->copyright

The copyright notice of the feed.

$feed->modified

A DateTime object representing the last-modified date of the feed.

$feed->generator

The generator of the feed.

$feed->entries

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