Java using Amazon mws?

Question

I have problems understanding how to use the amazon mws java library. I was able to implement it and I can call ListMatchingProducts and it prints me some xml into the console. But how do I get just parts from it, like product title for example? I just getting into programming and probably I just dont understand some basics of api usage here. please help me out. This is how I call the search method:

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

And this is an excerpt from the amazon api class I want to use:

         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) {

Answer 1

got it working myself. I just needed to access public static ListMatchingProductsResponse response; and convert it to xml. not that difficult actually.
