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。
