NAME

XML::FeedLite - Perl extension for fetching Atom and RSS feeds with minimal outlay

VERSION

$Revision: 1.5 $

SYNOPSIS

use XML::FeedLite;

DESCRIPTION

This module fetches and processes Atom and RSS-format XML feeds. It's designed as an alternative to XML::Atom, specifically to work better under mod_perl. This module requires LWP::Parallel::UserAgent.

SUBROUTINES/METHODS

new - Constructor

  my $xfl = XML::FeedLite->new("http://www.atomenabled.org/atom.xml");

  my $xfl = XML::FeedLite->new([qw(http://www.atomenabled.org/atom.xml
                                   http://slashdot.org/slashdot.rss)]);

  my $xfl = XML::FeedLite->new({
			        'timeout'    => 60,
                                'url'        => 'http://www.atomenabled.org/atom.xml',
                                'http_proxy' => 'http://user:pass@webcache.local.com:3128/',
			       });

 Options can be: url        (optional scalar or array ref, URLs of feeds)
                 timeout    (optional int,      HTTP fetch timeout in seconds)
                 http_proxy (optional scalar,   web cache or proxy if not set in %ENV)
                 proxy_user (optional scalar,   username for authenticating forward-proxy)
                 proxy_pass (optional scalar,   password for authenticating forward-proxy)
                 user_agent (optional scalar,   User-Agent HTTP request header value)


  Very often you'll want to use XML:::FeedLite::Normalised instead of this baseclass.

http_proxy - Get/Set http_proxy

$xfl->http_proxy("http://user:pass@squid.myco.com:3128/");

proxy_user - Get/Set proxy username for authenticating forward-proxies

This is only required if the username wasn't specified when setting http_proxy

  $xfl->proxy_user("myusername");

proxy_pass - Get/Set proxy password for authenticating forward-proxies

This is only required if the password wasn't specified when setting http_proxy

  $xfl->proxy_pass("secretpassword");

user_agent - Get/Set user-agent for request headers

$xfl->user_agent("Feedtastic/1.0");

timeout - Get/Set timeout

$xfl->timeout(30);

url - Get/Set DSN

$xfl->url("http://das.ensembl.org/das/ensembl1834/"); # give url (scalar or arrayref) here if not specified in new()

Or, if you want to add to the existing url list and you're feeling sneaky...

push @{$xfl->url}, "http://my.server/das/additionalsource";

reset - Flush bufers, reset flags etc.

$xfl->reset();

entries - Retrieve XML::Simple data structures from feeds

my $entry_data = $xfl->entries();

meta - Meta data globally keyed on feed, or for a given feed

my $hrMeta     = $xfl->meta();
my $hrFeedMeta = $xfl->meta("http://mysite.com/feed.xml");

title - The name/title of a given feed

my $title = $xfl->title($feed);

fetch - Performs the HTTP fetch and processing

$xfl->fetch({
             #########
             # URLs and associated callbacks
             #
             'url1' => sub { ... },
             'url2' => sub { ... },
            },
            {
             #########
             # Optional HTTP headers
             #
             'X-Forwarded-For' => 'a.b.c.d',
            });

statuscodes - Retrieve HTTP status codes for request URLs

my $code         = $xfl->statuscodes($url);
my $code_hashref = $xfl->statuscodes();

max_req - set number of running concurrent requests

$xfl->max_req(5);
print $xfl->max_req();
