I guess I was to tired when I wrote my previous email, sorry. Anyway, I read the different discussions when the appeared on the list. Last time it was suggested to use the time instead of the full message for hashing to decide on new content. This is supposed to work around problems like added comments and so forth... Now I look at my problem and the complete messages in the xml file are unchanged! No new tags added, no content changed.=20 But Gnus does, nevertheless, create a different hash, apparently because it incorporates the date of the file on disk into the hash! Thus, even a "touch feed.xml" on my local disk will "create" new entries in the RSS group. This is something, I believe, that we should get right (i.e. not use the date of the file). Disclaimer: I might have no idea what I am talking about with respect to RSS and nnrss.
