最近做了一个小工具，可以将XML和Excel之前互转。
里面用到的XML读写库是tinyxml，在Excel2010上运行，请先确保装了Excel，而不是WPS。
代码写的比较挫，一大坨，最近忙也懒得去做优化了。
github地址：XML与Excel互转工具
目前只支持ANSI格式的Excel文件与ANSI格式的XML文件互转。由于在写的时候，里面的存储方式都是CString，默认为ANSI格式，所以哪怕里面把文字转成了UTF8，再保存到CString中也还是被认为是ANSI，这时候就会出现乱码，接下来如果有时间我会把这个问题修复。
直接讲讲代码吧。
读写xml，调用的是tinyxml的接口，核心部分代码都在这下面了，比较挫，分享给大家，希望有帮助。
