the errors and provide information to help you to resolve them
as shown in this tutorial:
1. Go to Feed Validation Service at w3.org.
2. Click the "Validate by Direct Input" tab. You see a bigger input box for you to enter the Atom XML directly.
3. Enter the following invalid Atom XML:
<feed xmlns="http://www.w3.org/2005/Atom"> <title>World News</title> <subtitle>This is an example of an RSS feed.</subtitle> <updated>2029-07-31 12:29:29</updated> <link rel="self" href="http://www.world-news.com/"/> <id>http://www.world-news.com/</id> <editor> <name>John Doe</name> </editor> <entry> <title>Breaking News!</title> <link rel="alternate" href="http://www.world-news.com/news/53f933c5395f"/> <id>http://www.world-news.com/news/53f933c5395f</id> <updated>2029-09-15T00:00:00Z</updated> <summary>Here is a breaking news that is still on going...</summary> </entry> </feed>
3. Click the "Check" button. You see the validation errors:
Sorry - This feed does not validate. line 4, column 29: updated must be an RFC-3339 date-time: 2029-07-31 12:29:29 [help] <updated>2029-07-31 12:29:29</updated> ^ line 7, column 1: Undefined feed element: editor [help] <editor> ^ line 16, column 1: Missing entry element: author [help] </entry> ^ In addition, interoperability with the widest range of feed readers could be improved by implementing the following recommendations. line 5, column 53: Self reference doesn't match document location [help] <link rel="self" href="http://www.world-news.com/"/> ^ line 14, column 31: Implausible date: 2029-09-15T00:00:00Z [help] <updated>2029-09-15T00:00:00Z</updated>
