NAME¶
Feed::Find - Syndication feed auto-discovery
SYNOPSIS¶
use Feed::Find;
my @feeds = Feed::Find->find('http://example.com/');
DESCRIPTION¶
Feed::Find implements feed auto-discovery for finding syndication feeds,
given a URI. It (currently) passes all of the auto-discovery tests at
http://diveintomark.org/tests/client/autodiscovery/.
Feed::Find will discover the following feed formats:
- •
- RSS 0.91
- •
- RSS 1.0
- •
- RSS 2.0
- •
- Atom
USAGE¶
Feed::Find->find($uri)¶
Given a URI
$uri, use a variety of techniques to find the
feeds associated with that page. If
$uri itself points to
a feed (i.e., if the
Content-Type of the response is a recognized feed
type), returns
$uri.
Returns a list of feed URIs.
The following techniques are used:
- 1. <link> tag auto-discovery
- If the page contains any <link> tags in the
<head> section, these tags are examined for recognized feed
content types. The following content types are treated as feeds:
application/x.atom+xml, application/atom+xml,
application/xml, text/xml, application/rss+xml, and
application/rdf+xml.
- 2. Scanning <a> tags
- If the page does not contain any known <link>
tags, the page is then scanned for <a> tags for links to URIs
with certain file extensions. The following extensions are treated as
feeds: .rss, .xml, and .rdf.
Note that this technique is employed only if the first technique
returns no results.
Feed::Find->find_in_html(\$html [, $base_uri ])¶
Given a reference to a string
$html containing an HTML
page, uses the same techniques as described above in
find to find the
feeds associated with that page.
If you know the URI of the page, you should provide it in
$base_uri , so that relative links can be properly made
absolute.
Feed::Find will attempt to determine the correct base URI,
but unless that URI is specified in the HTML itself (in a
"<meta>" tag), you'll need to supply it yourself.
Returns a list of feed URIs.
