I have a XML atom feed from an affiliate that I need to...

Parse
Store (in a database I'm not sure how to build from the XML)
Display on my site the elements I choose to


I'm not sure the best forum to post this in.

I'm pretty sure it will take a combination of PHP & SQL I just don't know where to start.
As you have probably figured out my skills at this part of website design are minimal.

Any input would be greatly appreciated.
Thanks
