两个html页面合并_html转word c++
OpenXML是一个基于XML的Office文档格式，包括docx、excel、pptx以及图表等格式，该规范是由微软开发并发布的。虽然OpenXML功能很强大，但是在实际开发过程中，我们还是会面临不少困难，毕竟其功能比较基础。
所以今天给大家推荐一个使用 Open XML 文档（DOCX、XLSX 和 PPTX）编程接口，在此基础上进行了很多优化、并实现DOCX、PPTX、Html等文件合并、拆分、互相转换等实用的功能。
项目简介
这是一个Open XML 文档编程接口开发的，并扩展了Open XML SDK的功能。
它支持以下功能：
1、将docx、pptx文件拆分为多个文件；
2、将多个docx、pptx文件合并为一个文件；
3、使用XML数据模板生成docx文件；
4、doxc文档高保值转换为Html页面；
5、html页面高保值转换为docx文档；
6、支持正则表达式搜索和替换 DOCX/PPTX 中的内容；
7、支持docx、pptx文件，管理跟踪修订，包括检测跟踪修订和接受跟踪修订；
8、更新 DOCX/PPTX 文件中的图表，包括更新缓存数据以及嵌入的 XLSX；
9、对比两个doxc文件，并生成带有修订跟踪标记的doxc文档，并支持检索修订列表；
10、支持从doxc文档检索，包括使用样式、层次结构、使用的语言与字体；
11、与直接编写标记相比，使用简单得多的代码编写XLSX文件，包括一种可以编写数百万行的XLSX文档的流式方法。
12、支持从Excel提取数据，包括内容的格式。
技术架构
1、平台：net45;net46;netstandard2.0 开发
2、开发工具：Visual Studio 2017
