Question

I can’t use a & in the tag of rss feed item, because when I do I always get the error

error on line 1 at column 1337: EntityRef: expecting ';'

but If I don’t use & in the tag then everything is ok.

E.g this doesn’t work:

<?xml version="1.0" encoding="UTF-8" ?>
<rss version="2.0">
<channel>
  <title>Borken RSS feed</title>
  <description>Broken RSS Feed is broken.</description>
  <link>http://example.org</link>

[...]
    <link>
    
    </link>
    <guid>
    
    </guid>
[...]

Answer 1

You have to escape all special characters. & and should look like &

Using php, that would look like: htmlspecialchars($text);

Chars that need to be escaped: <, >, “, &, and possibly others…
