php create an rss feed (lets say for a poll website)

Question

How do i create my custom RSS feed generator with php ?

Hopefully i will like to avoid use of any libraries(if possible).

Lets say i have a poll website where users create polls.

lets say I want to record the events : 1)when people create a poll a function will get provoked containing the code ti write RSS to XML file. etc etc events.

Lets i want to record 3 things: 1)username of the user who created the poll contained within a variable lets say $username. 2)The text of the poll lets contained in the variable $text 3)The options : an array containing all the options lets say the name of the array be $options

How do i write it maybe using the DOMelment function in php ?

Why avoid libraries? Something like Zend_Feed_Writer can save you tons of work.
