Importing XML into MySQL table?

[multiz_com]

I'm a little new to MySQL -- so, help is very much appreciated.Does anyone know how I could import every item from an XML feed into a MySQL table and then have the items automatically delete after 24 hours, and if I imported another XML feed, it wouldn't replace the existing items but add to it (and wouldn't add duplicates)?I would like to do all of this with PHP.Thanks if you can help or point me the correct direction.
