WooCommerce - Auto Update Stock Quantities via a XML Feed

I need a plug-in created which will allow me to update stock quantities in my woocommerce store via a Live XML Feed from my supplier which will be downloaded via URL. The plug-in will also need to set stock quantity to 0 if the product is no longer in the XML. I would like to be able to manually start the plug-in when needed as well as have it run via a cron job every 5 mins. XML structure is as follows: <catalogue> <product> <products_id>123456</products_id> <model>abc123</model> <quantity>99</quantity> <weight>422.00</weight> <products_barcode>1234567890012</products_barcode> </product> </catalogue> only need to use model and quantity (model = sku). If you need any more info please contact me.
