C++ —— Tinyxml2在Vs2017下相关使用1（附源码）

 

tinyxml2简介

     TinyXML2是一个简单，小巧，高效，C++XML解析器，可以很容易地集成到其他程序中。TinyXML-2解析一个XML文档，并从中构建一个 可以读取、修改和保存的文档对象模型 （DOM）。XML代表“可扩展标记语言”。这是一个通用目的 用于描述任意数据的人类和机器可读标记语言。 为存储应用程序数据而创建的所有随机文件格式都可以 全部替换为 XML。一个解析器可以解决所有问题。

 

源码下载

     Github - Tinyxml2源码下载地址

     一般来说，下载源码后无需编译仅将其中的tinyxml2.cpp、tinyxml2.h包含在自己的项目中就可以使用了。
     （若需构建库使用CMake构建源码，然后利用Vs仅编译tinyxml2项目。）

 

使用tinyxml2注意事项

     TinyXML与实体

TinyXML认得预定义的特殊“字符实体”，即:
	& &
	< <
	> >
	" "
	' ‘
这些在XML文档读取时都会被辨认出来，并会被转化成等价的UTF-8字符。
