[wp-hackers] How To Get Completely Processed Body Of Blog Posts?

[Otto]

You can skip the setup_postdata(), the global, the reset...

$mypost = get_post(whatever);
$content = apply_filters('the_content', $mypost->post_content);

Note: Badly made plugins that use shortcodes for inappropriate things
will complain at you about doing this. I've seen cases where
processing the_content filter will a) Add items to a cart in a
shopping plugin, b) make a site do heavy processing because it's doing
too much database work for the shortcode, c) make duplicate posts on
twitter/facebook/other...

Basically, many plugin authors don't know that shortcodes shouldn't do
heavy lifting or that they can be called more than once on a page,
etc. So expect issues whenever you use the_content filter in this way.
However, that's their problem, not yours.
