Entities can use hexadecimal notation too...

function cdataize($content)
{
$content = preg_replace('/\&\#([0-9]+);/','<![CDATA[&#\\1;]]>',$content);
$content = preg_replace('/\&\#x([0-9A-F]+);/i','<![CDATA[&#\\1;]]>',$content);
return($content);
}

There are also named entities, like "&emdash;", but I don't think RSS
defines any such entities apart from the five standard XML ones.
