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
21       ·   RSS 1.0
22
23       ·   RSS 2.0
24
25       ·   Atom
26

USAGE

28   Feed::Find->find($uri)
29       Given a URI $uri, use a variety of techniques to find the feeds
30       associated with that page. If $uri itself points to a feed (i.e., if
31       the Content-Type of the response is a recognized feed type), returns
32       $uri.
33
34       Returns a list of feed URIs.
35
36       The following techniques are used:
37
38       1. <link> tag auto-discovery
39           If the page contains any <link> tags in the <head> section, these
40           tags are examined for recognized feed content types. The following
41           content types are treated as feeds: application/x.atom+xml,
42           application/atom+xml, application/xml, text/xml,
43           application/rss+xml, and application/rdf+xml.
44
45       2. Scanning <a> tags
46           If the page does not contain any known <link> tags, the page is
47           then scanned for <a> tags for links to URIs with certain file
48           extensions. The following extensions are treated as feeds: .rss,
49           .xml, and .rdf.
50
51           Note that this technique is employed only if the first technique
52           returns no results.
53
54   Feed::Find->find_in_html(\$html [, $base_uri ])
55       Given a reference to a string $html containing an HTML page, uses the
56       same techniques as described above in find to find the feeds associated
57       with that page.
58
59       If you know the URI of the page, you should provide it in $base_uri, so
60       that relative links can be properly made absolute. Feed::Find will
61       attempt to determine the correct base URI, but unless that URI is
62       specified in the HTML itself (in a "<meta>" tag), you'll need to supply
63       it yourself.
64
65       Returns a list of feed URIs.
