Open Xml Sdk创建公式

距离上一篇openxml的文章已经过去很久了,这段时间一直忙于openxml来自动生成word。把自动生成word的心得写出来,这一篇就写插入word2007数学公式吧。

       在写插入数学公式之前先回顾一下openxml的相关知识,openxml是基于xml和zip协议的文档描述格式。所以我们可以将word的中一个个组成看成一个个标签对,自动生成word的内容就是在生成一个个标签对,然后插入内容,插入到文档标签中。使用openxml生成word速度比微软自带的接口速度快了十几倍,不过稍显不足的是word2003不是openxml格式的。

       Paragraph是openxml中的段落标签,这个标签是word的基本组成部分,word中除了表格标签外,其他的内容都是放在Paragraph中的。

OfficeMath即数学公式标签。

下面是示例代码,这里先只写一个简单的公式,有空我在把常用的公式整理出来
