6 Feed::Find - Syndication feed auto-discovery
7
9 use Feed::Find;
10 my @feeds = Feed::Find->find('http://example.com/');
11
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
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.
