说明：  今天有点郁闷，不想干活。整理代码的时候，看到了这个好久之前写的代码，于是想整理出来供大家拍砖。XML的解析对于.Net平台那真是太简单不过了，感谢微软。但对于C++语言的XML解析就没那么容易了。有一个开源的XML4C是IBM的,功能强大，但代码大的有几M,而且对于GB2312的支持有问题，据说能解决，但可能是我天生愚钝，当初我花了2周时间也没搞定，最后放弃，自己写了一个。咦？还能跑起来，也能跨平台:)。 写这个XML解析类，以功能最简单，最实用，最常用的功能为原则，因为只能解析，查找，没有XML文档生成器。如果需要生成XMl文档，还是自己拼凑字串吧。
(today a bit depressed, do not want to work. Finishing the code, to see this a long time before writing code, so to put them down for you Bozhuan. XML for Analysis. Net platform that really is too simple, but I thank Microsoft. But for the C language XML parser will not be so easy. Have a revenue XML4C IBM and powerful, but the code with a large number M, GB2312 but for the support of a problem, was resolved, but I may be born a blunt, I spent the first two weeks did not get, abandon, wrote one. What's this? Can run, can be cross-platform :). Wrote this XML analytical categories, in order to function the simplest, most practical, the most commonly used function of the principle that only analyze, and find, not XML generator. If Generation XMl document, or your own patchwork string it.)
