Oscommerce XML Import - Export

Oscommerce XML Import - Export Export from OSC to AS for Customer and Order information Import from AS to OSC for Product information (AS = Administration Software) From OSC there must be a possibility (click on a link) to export (new) customers and orders in an XML file. The exported orders in the shop get a certain status so they won’t get exported with the next update. The XML file can be download by the shop owner or put in a predefined map on the webserver. (catalog/temp). (this part of the project is 75% finished) From AS there will be a XML export file of products. This file will be put in a predefined map on the webserver. (catalog/temp). This part will be done by AS programmer. In OSC there must be a link to pick up the XML file and enter it into the database. Existing products will be updated, new products will be added and products with out stock or product that are “end of live” will get the status “inactive”. If a product has a manufacturer this manufacturer ill be added to the table manufacturer or when it is a existing manufacturer information will be updated. Categories from AS will be created in OSC and products will be linked to the right category. The format for the XML file from AS will be made to follow OSC format. I need somebody who knows OSC and XML and can think with me.
