ARG! After spending so much time making sure my RSS feeds are valid XML, I have run into a limitation of the seemingly most preeminent RSS feed validator online.
It bombs out right at about 200K. If the feed is longer, it is invalid. There is no warning that this limitation is reached.
FEED Validator by Mark Pilgrim and Sam Ruby
You can attempt to validate my feed, but if it is over 200K (which it currently is), it will fail.
However, you can attempt to parse the feed as XML, as in my C# example code, and it will parse just fine.
Since validating my RSS feed with the copy/pasting from Word has been such a major issue, I added a main link to validate the RSS feed via “FEED Validator”. This link has been removed.
Update: Previously the mentioned limit was about 400K, it is actually closer to 200K. This is due to reporting error with U8-DOS encoding in UltraEdit.
