NAME

Mojo::Feed - Mojo::DOM-based parsing of RSS & Atom feeds

SYNOPSIS

use Mojo::Feed;
use Mojo::File qw(path);

my $feed = Mojo::Feed->new->parse(file => path("atom.xml"));
print $feed->title, "\n",
  $feed->items->map('title')->join("\n");

$feed = Mojo::Feed->new( body => $string );
$feed = Mojo::Feed->new( url => $rss_url );

my $feed = Mojo::Feed->new(
  url => "https://github.com/dotandimet/Mojo-Feed/commits/master.atom");
say $feed->title;
$feed->items->each(
  sub { say $_->title, q{ }, Mojo::Date->new($_->published); });

DESCRIPTION

Mojo::Feed is an Object Oriented module for identifying, fetching and parsing RSS and Atom Feeds. It relies on Mojo::DOM for XML/HTML parsing. Date parsing is done with HTTP::Date.

Mojo::Feed represents the parsed RSS/Atom feed; you can construct it by setting an XML string as the body attribute, by setting the file or url attributes to a Mojo::File or Mojo::URL respectively, or by using a Mojo::Feed::Reader object.

ATTRIBUTES

Mojo::Feed implements the following attributes.

body

The original decoded string of the feed.

dom

The parsed feed as Mojo::DOM object.

source

The source of the feed; either a Mojo::File or Mojo::URL object, or undef if the feed source was a string.

title

Returns the feed's title.

description

Description of the feed, filled from channel description (RSS), subtitle (Atom 1.0) or tagline (Atom 0.3)

link

Web page URL associated with the feed

items

Mojo::Collection of Mojo::Feed::Item objects representing feed news items

entries

Alias name for items.

subtitle

Optional feed description

author

Name from author, dc:creator or webMaster field

published

Time in epoch seconds (may be filled with pubDate, dc:date, created, issued, updated or modified)

url

A Mojo::URL object from which to load the file. If set, it will set source. The url attribute may change when the feed is loaded if the user agent receives a redirect.

file

A Mojo::File object from which to read the file. If set, it will set source.

is_valid

True if the top-level element of the DOM is a valid RSS (0.9x, 1.0, 2.0) or Atom tag. Otherwise, false.

feed_type

Detect type of feed - returns one of "RSS 1.0", "RSS 2.0", "Atom 0.3", "Atom 1.0" or "unknown"

METHODS

Mojo::Feed inherits all methods from Mojo::Base and implements the following new ones.

new

my $feed = Mojo::Feed->new;
my $feed = Mojo::Feed->new( body => $string);

Construct a new Mojo::Feed object.

to_hash

my $hash = $feed->to_hash;
print $hash->{title};

Return a hash reference representing the feed.

to_string

Return a XML serialized text of the feed's Mojo::DOM node. Note that this can be different from the original XML text in the feed.

is_feed_content_type

Accepts a mime type string as an argument; returns true if it is one of the accepted mime-types for RSS/Atom feeds, undef otherwise.

find_feed_links

Accepts a Mojo::Message::Response returned from an HTML page, uses its dom() method to find either LINK elements in the HEAD or links (A elements) that link to a possible RSS/Atom feed.
