[issue] Double-escaping tags for the RSS feed.

When I’m posting a code example in my texpattern blog, something really simple along the lines of <code><h1></code>, I run into trouble w/ my RSS feed.

Textpattern doesn’t double-escape the < and > characters for the RSS feed, so NetNewsWire and other newsreaders interpret the <code><h1></code> tag as a true <code><h1></code>, styling the rest of the entry as an h1.

Same thing happens when I go ahead and do the & lt; and & gt; around the h1 instead of < and > (spaces included to psych out textile).

What Textpattern needs to do to make it proper in the RSS feed is make it look like this: <code>&amp;lt;h1&amp;gt;</code>

Does anybody know how to deal w/ this?

Re: [issue] Double-escaping tags for the RSS feed.

Yes, I had the same problem, escaping is broken for the RSS feed (it works fine for Atom however). I changed textpattern/publish/rss.php to fix this. These lines are responsible for escaping there:

$Body = rss_safe_hed($Body);

$Body = preg_replace(array(‘/&lt;/’,’/&gt;/’,”/’/”,’/”/’), array(‘&amp;lt;’,’&amp;gt;’,’&amp;#039;’,’&amp;quot;’),$Body);
// encode bare ampersands
$Body = preg_replace(“/&(?!1+;|\w+;)/i”,’&amp;amp;’, $Body);

I replaced them by this one:

$Body = preg_replace(array(‘/&/’,’/&lt;/’,’/&gt;/’,”/’/”,’/”/’), array(‘&amp;amp;’,’&amp;lt;’,’&amp;gt;’,’&amp;#039;’,’&amp;quot;’),$Body);

Unless I am really missing something this is what it should’ve been.

PS: Posting code in this forum is hard :-(
