A method for parsing purchase information from code in a Web page. The method includes detecting at least one known product keyword and at least one product data string following that product keyword and being associated with that product keyword. The product data string can be a descriptor for the product keyword for one product in the purchase. The method also includes detecting at least one known transaction keyword and at least one transaction data string following that transaction keyword and being associated with that transaction keyword, the transaction data string being a descriptor for the transaction keyword. The data type of the descriptors can be checked to determine if they are of the same type as the corresponding product or transaction keyword. These processes can be repeated for all of the data strings in the HTML page, and this detected purchase information can be placed into an organized form.
