怎么用Google APIs和Google的应用系统进行集成(8)-怎么把Google Blogger（博客）的JSON Schema转换成XML的Schema(XSD)

如何用Google APIs和Google的应用系统进行集成(8)----如何把Google Blogger（博客）的JSON Schema转换成XML的Schema(XSD)？

在Google RESTFul API中，Google Blogger API（Google博客API）应该和我们的生活离得最近；因为几乎很多人每天都在看博客，都在写博客，都听说过博客。在前面的Google的应用系统进行集成(5）和Google的应用系统进行集成(6)的系列文章中，我们提到了如何把Google Calendar和Google Tasks的JSON Schema转换成XML的XSD的Schema；从博客的访问量来看，还是有很多志同道合的朋友们对这个比较感兴趣，因此，这个章节，我继续给大家奉献和分享一下如何把Google Blogger的JSON Schema转换成XML的Schema(XSD)。首先我们先列出Google Blogger的JSON的Schema（https://www.googleapis.com/discovery/v1/apis/blogger/v3/rest）

 

 

那么，如何把Google Blogger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。
