I forgot to mention that the html entered may be just a part of HTML, so assuming presence of "<html" tag will not work.

This is HTML: `Please use <code>...</code> tags around your code.` [download] This is text: `Please use <code>use strict;</code> in your code.` [download] How can one possibly correctly identify them programatically? PS - This is the reason Atom is better than RSS. RSS doesn't provide a mean of specifying the content type, so it can't distinguish between text and HTML content. Clients have to guess. You could take a peek at how RSS clients do it, but I suspect they might work with less ambiguous content than you.	[reply] [d/l] [select]
