我正在尝试使用Boto来阅读亚马逊MWS响应以获取ID的匹配产品。我的连接工作正常，并且能够获得结果，但在尝试解析结果时遇到问题。看起来Boto内置了结果解析器，例如Response和ResponseFactory。我只是无法弄清楚如何将信息传递给这些方法，所以我可以实现一些预先构建的代码。
此代码：
mws = MWSConnection(accessKeyId,secretKey,Merchant=merchantId)
response = mws.list_matching_products(MarketplaceId=marketplaceId,Query="Beanie Babies")
打印出这个字符串：

我确信我可以弄清楚如何使用XML解析器解析XML，但似乎Response和ResponseFactory会让我的生活变得更轻松。我找不到任何真实世界的例子来复制和播放，因为我没有编程背景我不能完全理解所有文档。任何帮助将不胜感激。
