Exports your OpenCart 4 catalogue as a token guarded product XML document for İdefix. Each product carries StockCode, Barcode, Isbn, Mpn, Name, Description, Brand, the full category path, ListPrice and SalePrice, Currency, a VatRate derived from the product's OpenCart tax class (so a 0% class such as books exports as 0), Quantity, the product URL, up to ten images, and every OpenCart product attribute inside a generic Attributes block. Optional attribute mappings add Author, Publisher and PageCount for book catalogues. Identifiers are read from OpenCart 4.1's product_code table and from the legacy product columns, whichever is present, so ISBN and EAN survive both fresh installs and stores upgraded from 4.0. Specials come from product_discount rows and products are read in batches of 250 so large catalogues do not exhaust memory.
