XML data feed into OSCommerce

client will be receiving monthly XML data file f with all product updates etc. They need to be able to import this data feed into OSCommerce without having to know any code. I am looking for someone to write a script to enable this. There are numerous product attributes as well, not all of which will appear in the xml file-so I am not sure if this makes it more difficult. ## Deliverables XML file, upload via GUI interface button in OSCommerce- which updates all products, including images and descriptions. ? ? There are numerous product attributes which are not part of the XML file- and need to remain working and in place on the product pages
