>No. Rss 2.0 includes a bunch of requires namespaces. If it doesn't say RSS 2.0 then it's not actuall RSS 2.0 but something else.
I finally finished the part to get the last update date from several feeds. When looking at yours, I see that it says 2.0 but I can't find the lastBuildDate in the channel node. In that situation, is my only way to extract all item node and get the most up to date pudDate value?
