NAME

6       Feed::Find - Syndication feed auto-discovery
7

SYNOPSIS

9           use Feed::Find;
10           my @feeds = Feed::Find->find('http://example.com/');
11

DESCRIPTION

13       Feed::Find implements feed auto-discovery for finding syndication
14       feeds, given a URI. It (currently) passes all of the auto-discovery
15       tests at http://diveintomark.org/tests/client/autodiscovery/.
16
17       Feed::Find will discover the following feed formats:
18
19       * RSS 0.91
20       * RSS 1.0
21       * RSS 2.0
22       * Atom
23

USAGE

25       Feed::Find->find($uri)
26
27       Given a URI $uri, use a variety of techniques to find the feeds associ‐
28       ated with that page. If $uri itself points to a feed (i.e., if the Con‐
29       tent-Type of the response is a recognized feed type), returns $uri.
30
31       Returns a list of feed URIs.
32
33       The following techniques are used:
34
35       1. <link> tag auto-discovery
36           If the page contains any <link> tags in the <head> section, these
37           tags are examined for recognized feed content types. The following
38           content types are treated as feeds: application/x.atom+xml, appli‐
39           cation/atom+xml, application/xml, text/xml, application/rss+xml,
40           and application/rdf+xml.
41
42       2. Scanning <a> tags
43           If the page does not contain any known <link> tags, the page is
44           then scanned for <a> tags for links to URIs with certain file
45           extensions. The following extensions are treated as feeds: .rss,
46           .xml, and .rdf.
47
48           Note that this technique is employed only if the first technique
49           returns no results.
50
51       Feed::Find->find_in_html($html [, $base_uri ])
52
53       Given a string $html containing an HTML page, uses the same techniques
54       as described above in find to find the feeds associated with that page.
55
56       If you know the URI of the page, you should provide it in $base_uri, so
57       that relative links can be properly made absolute. Feed::Find will
58       attempt to determine the correct base URI, but unless that URI is spec‐
59       ified in the HTML itself (in a "<meta>" tag), you'll need to supply it
60       yourself.
61
62       Returns a list of feed URIs.
