说明：  C++标准库中没有操作XML的方法，用C++操作XML文件必须熟悉一种函数库，LIBXML2是其中一种很优秀的XML库，而且它同时支持多种编程语言；2)LIBXML2库的Tutorial写得不太好，尤其是编码转换的部分，不适用于中文编码的转换；3)网上的大多数关于Libxml2的介绍仅仅是翻译了自带的资料，没有详细介绍如何在windows平台下进行编程，更很少提到如何解决中文问题。
(C++ standard library no way to manipulate XML, C++, XML documents must be familiar with the operation of a library, LIBXML2 is one very good XML library, and it supports multiple programming languages Tutorial 2) LIBXML2 library written not very good, especially the transcoding section does not apply to Chinese encoding conversion 3) most online presentation about Libxml2 merely translated the information that comes with no details of how to program in the windows platform, more little mention of how to solve the Chinese problem.)
