There are two things I can suggest:
1. Using the DOM XML functions to extract the values (See
http://au3.php.net/domxml), then use the strip_tags() functions.
or
2. Use Regular expressions to extract the html tags from the XML before
you use rss2array
e.g.
// Remove all <p> tags
$xml = preg_replace('/<p(.*)?>(.*)?<\/p>/', "$2", $xml);
//Remove all <font> tags
$xml = preg_replace('/<font(.*)?>(.*)?<\/font>/', "$2", $xml);
//etc...
