In php, Prepare string and create XML/RSS Feed
I want to create my own RSS/XML feed.  I fetch data from the database to display, but keep getting invalid character errors.  If the string has an ampersand or other strange characters in it, the XML will be invalid.

I tried using urlencode and htmlentities, but these don't capture all possible characters which need to be escaped.  Does anyone know of a PHP function which will prepare a string for XML output?
