Hi, By default, the atoms feed produced by wikipedia is not valid: http://feedvalidator.org/check.cgi?url=http%3A%2F%2Fmeta.wikimedia.org%2Fw%… There are 3 errors. The first one, "missing of namespace", is easy to fixed. 'xmlns="http://purl.org/atom/ns#"' must be add to the "feed" element printed by outHeader method of the AtomFeed class (line 153 of the 1.3beta5 version of wikipedia). The second one, "Undefined entry element: comment" seems to be a bug of the validator: Comments are not elements. The last one is more complexe. In an atom feed, each entry must have an id. This id must identify the entry: http://www.mnot.net/drafts/draft-nottingham-atom-format-02.html#rfc.section… Has someone a suggestion about how-to produce a good Id element? -- Michaël P. gpg: D4C8 F73D A000 71C7 44EF 27E6 8982 4991 7126 3CE3
