Amazon XML Product Feed Sample

I need PHP code that will create a couple of sample XML product feeds for adding, editing, and removing products from my amazon seller central store.? I have the XSD files for you to read and base this off of.? I will need the code that creates the sample files to include every possible option that the XSD offers. I have code that creates other XML files in the same format that I need these created in and the XSDs that match these files.? I will provide them so you can see what I need matched. Finally, I am not very good at reading XSDs so I'm not even positive that they provide the options for editing and deleting products so I'll need you to take a look at the XSDs during the grace period and let me know.
