Plugin that will import products from an XML feed into WooCommerce

We require a plugin that will import products from an XML feed into WooCommerce (YITH WOOCOMMERCE MULTI VENDOR). The plugin has to run via cron every few hours (we will set this) to update prices and stock of the imported products. It must do the following: [login to view URL] products that are not already in database (See appendix bellow for requirements) [login to view URL] products that are already in database (See appendix bellow for requirements) [login to view URL] products that are in database but not in the XML [login to view URL] multiple XML feeds. One for each vendor. [login to view URL] XML file for errors before processing it. [login to view URL] vendors XML feed must import the products under his account in the multivendor eshop. [login to view URL] must run each import/update in serial mode, not all at the same time - parallel - in order to reduce server load. (eg. run for vendor1 when it finishes then run for vendor2 etc) [login to view URL] has to be developed in such way that will allow us to update the WooCommerce installation [login to view URL] is MUST be developed using WooCommerce API and not using direct database/file manipulation. [login to view URL] cron job must have a token that we will define(hardcoded) for security reasons (eg. [login to view URL]). If the token is wrong the script must not run. XML specifications The XML feeds will have the format described here [login to view URL] (we need extra attributes: description, short description and discounted price. If there are more at the feed the system must simply ignore them), you can see a live example here: [login to view URL] It must have a function (even hardcoded) that will allow us to specify which XML feed is for each vendor and also allow us to disable specific vendors. Usage example We have 2 vendors at our multivendor eshop. Vendor 1: Name TEST, ID: 1 Vendor 2: Name TEST2, ID:2 and their XML feeds are at the urls: [login to view URL] & [login to view URL] We must be able to assign each vendor with his XML file. The imported products must be under each one's vendor account.
