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。
