Java使用亚马逊mws？

Question

我在理解如何使用 amazon mws java 库时遇到问题。我能够实现它，我可以调用 ListMatchingProducts 并将一些 xml 打印到控制台中。但是我如何从中获取部分内容，例如产品标题？我刚开始编程，可能我只是不了解这里的 api 使用的一些基础知识。请帮帮我。这就是我调用搜索方法的方式:

   searchF.setOnAction(new EventHandler<ActionEvent>() {
        @Override
        public void handle(ActionEvent event) {
            AmazonSearch.amazonSearch(searchF.getText());               
        }
    });

这是我想使用的亚马逊 api 类的摘录:

         invokeListMatchingProducts(service, request);

    }

    public static ListMatchingProductsResponse response;

    public static void invokeListMatchingProducts(MarketplaceWebServiceProducts service, 
            ListMatchingProductsRequest request) {
        try {

            response = service.listMatchingProducts(request);


            System.out.println ("ListMatchingProducts Action Response");
            System.out.println ("=============================================================================");
            System.out.println ();

            System.out.println("    ListMatchingProductsResponse");
            System.out.println();
            if (response.isSetListMatchingProductsResult()) {
                System.out.println("        ListMatchingProductsResult");
                System.out.println();
                ListMatchingProductsResult  listMatchingProductsResult = response.getListMatchingProductsResult();
                if (listMatchingProductsResult.isSetProducts()) {
                    System.out.println("            Products");
                    System.out.println();
                    ProductList  products = listMatchingProductsResult.getProducts();
                    java.util.List<Product> productList = products.getProduct();
                    for (Product product : productList) {
                        System.out.println("                Product");
                        System.out.println();
                        if (product.isSetIdentifiers()) {

                                System.out.println();

我自己搞定了。我只需要访问 public static ListMatchingProductsResponse response; 并将其转换为 xml。其实没那么难。
