Question: I want to be able to read any well-formed RSS/ATOM file. That would mean I would not not know the tags, start the loop and the fields. How do I go about doing it in PHP.

Thanks
Jean

Answer: 
You can try [Zend Framework's feed class](http://framework.zend.com/manual/en/zend.feed.html). 

But you should be more specific about your task..
You can use SimpleXML <http://php.net/manual/en/function.simplexml-load-string.php>
