前面说了一些Google API的介绍,但是在实际的开发当中,我们可能需要把Google RESTful API返回的JSON数据转换成XML数据输入到第三方系统,这在企业应用集成里面非常的常见。那么里面就有一个问题,如何确保转换后的XML数据格式是规范的,这就需要XML Schema(XML)来进行校验。现在关键是,我们只知道Google API的JSON的schema,但是Google RESTful并没有提供返回数据的XML的schema,那么XML的Schema将会是什么样子的呢?让我以Google Tasks API为例子。从下面的URL我们可以看到Google Tasks RESTFul的API JSON Schema的信息:https://www.googleapis.com/discovery/v1/apis/tasks/v1/rest

那么,如何把Google Tasks的JSON Schema转换成XML的XSD Schema?XML的Schema将会是什么样子的呢?请参考下面转换实现。

<?xml version='1.0' encoding='UTF-8'?>
