使用NOPI读取Word、Excel文档内容
使用NOPI读取Excel的例子很多，读取Word的例子不多。
Excel的解析方式有多中，可以使用ODBC查询，把Excel作为一个数据集对待。也可以使用文档结构模型的方式进行解析，即解析Workbook（工作簿）、Sheet、Row、Column。
Word的解析比较复杂，因为Word的文档结构模型定义较为复杂。解析Word或者Excel，关键是理解Word、Excel的文档对象模型。
Word、Excel文档对象模型的解析，可以通过COM接口调用，此类方式使用较广。（可以录制宏代码，然后替换为对应的语言）
也可以使用XML模型解析，尤其是对于2007、2010版本的文档的解析。
