Exports your OpenCart 4 catalogue as a token guarded product XML document for PTT AVM. Each product carries StockCode, Barcode, Mpn, Name, Description, Brand, the full category path, ListPrice and SalePrice, Currency, a VatRate derived from the product's OpenCart tax class, Quantity, an optional ShipmentCompany, the product URL, up to ten images, and every OpenCart product attribute inside a generic Attributes block. Identifiers are read from OpenCart 4.1's product_code table and from the legacy product columns, whichever is present. Specials come from product_discount rows and products are read in batches of 250 so large catalogues do not exhaust memory.
