I don’t know of any functionality provided for in the various RSS specifications for paging of content.
It’s basically a situation of providing a summary, or providing full content; trying to duplicate what you can do on your web site through RSS, I think you’re going to run into a lot of problems–not just from the specs, but from visitors to your site attempting to view your feed through the numerous kinds of feed readers out there.
Perhaps I haven’t explained it nicely.
I want the content tag of the rss feed to contain what is display on the front page of my blog. At the moment I can choose between a few sentences or the whole thing. On the front page I can control where it is truncated by using the more tag. So I want exactly that content of the front page syndicated in the feed, including or excluding the “more” hyperlink.
This is b2evo’s default behaviour. It will pass the entire article, or if the article has been paged it will pass the first part, along with the hyperlink to “Read more”
Ah, I see what you’re after now. As far as I can tell, WordPress handles rss files as something like individual posts, meaning that when syndicating full text, it outputs the content for each item as if on a single post page. Off-hand I’m not sure what it would take to modify this behavior. However, a possible workaround may be a plugin of mine I wrote for a similar problem:
http://guff.szub.net/the-excerpt-reloaded
If you installed this and replaced:
<?php the_content(); ?>
in your wp-rss2.php with my plugin’s tag:
<?php the_excerpt_reloaded(); ?>
and set WordPress to full text for your syndication feeds, you could specify how many words to output before adding the more link, as well as define which HTML tags to allow, etc.
