XML data feed

Hi everyone

This is my first thread started on wordpress, i simply always find an answer, so never had to write one before. In over 2 years ive grown to love WP so much im unable to even think of moving platforms. However recently i have been asked to create a data feed for my client.

My question is there any plugins that can create a custom data feed of my coupons and export the XML with fields required by my affiliates. for instance my affiliate asked me to submit a data feed in this format below. Is there any plugins in assisting this task. yes i know that it all depends on the theme ect.

<description>We could wax lyrical about the joys of eating cupcakes. We could quote Marie
Antoinette or that ever popular proverb. We could, but that would be boring and cheesy and these
cupcakes are anything but. We’ll cut to the delicious stuff and let you in on our heavenly deal: Get 4
divine chocolate or vanilla cupcakes with butter icing from Wildflour for only R22! That’s R5.50 a
cupcake, which is less than a litre of milk, the Sunday Times, an avocado, a cup of coffee, a bar of
soap, a loaf of bread and… a lot of other things.</description>
