Multiple channels in a single RSS xml - is it ever appropriate?
A typical xml file for an RSS feed starts with an "rss" element on the outermost level, and usually has a single "channel" element within it that represents the "feed" or "channel." Is there ever a situation where it is appropriate to use multiple channels within an element, like the following? <rss> <channel> ... <item> ... </item> </channel> <channel> ... </channel> </rss> From here : Subordinate to the <rss> element is a single <channel> element, which contains information about the channel (metadata) and its contents. So there not only is no use case for that – it isn't even allowed. 来源:
