I've created an RSS 2.0 Feed for a friend of mine using PHP and MySQL. The author writes a ton of articles. I've worked out all the details of creating the feed in PHP, except for escaping characters for XML/RSS.
What's the best way to escape Text/HTML for an RSS 2.0 Feed using PHP? Can RSS descriptions contain HTML?
And... How might I escape out those "Mikrsooft" characters that I know the author will copy into the RSS descriptions?
