Feed::Find(3) User Contributed Perl Documentation Feed::Find(3)NAMEFeed::Find - Syndication feed auto-discovery
SYNOPSIS
use Feed::Find;
my @feeds = Feed::Find->find('http://example.com/');
DESCRIPTIONFeed::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.
