TinyXML读写XML文件

最近要用c++来读写配置文件，和自己的需要记录的数据，这这东西比存在数据库里面好用，但是唯一不爽的一点是可维护性太差，修改字段后太难处理了，没有php拿到参数方便，可以直接以字符串来索引查找参数的值，只能以相对位置，先拿到根目录，然后再根据相对位置查找。

这个东西的好处是可以直接拿来源码用，只有6个文件，放到你的工程里就好了。

#include "tinystr.h"
#include "tinyxml.h"

void QuoteReadConfig::ReadConfig(const char* FilePath)
{
	
	TiXmlDocument *myDocument = new TiXmlDocument(FilePath);
	if (myDocument->ErrorId() > 0)
		return;
	myDocument->LoadFile();

	TiXmlElement *QuoteConfig = myDocument->RootElement();
	TiXmlElement *Logdir = QuoteConfig->FirstChildElement();
	quoteConfig->logdir = Logdir->GetText();
	
	TiXmlElement *SetUpperNo = Logdir->NextSiblingElement();
	TiXmlElement *UpperChannelNo = SetUpperNo->FirstChildElement();
	TiXmlElement *UpperNo = UpperChannelNo->NextSiblingElement();
	TiXmlElement *PostID = UpperNo->NextSiblingElement();
	if (UpperChannelNo != NULL)
		quoteConfig->UpperChannelNo = UpperChannelNo->GetText();
	cout << quoteConfig->UpperChannelNo << endl;
	if (UpperNo != NULL)
		quoteConfig->UpperNo = UpperNo->GetText();
	if (PostID != NULL)
		quoteConfig->PostID = PostID->GetText();
	
	TiXmlElement *QuoteBusAddress = SetUpperNo->NextSiblingElement();
	TiXmlElement *BusName = QuoteBusAddress->FirstChildElement();
	TiXmlElement *IP = BusName->NextSiblingElement();
	TiXmlElement *Port = IP->NextSiblingElement();

		delete myDocument;
		myDocument = NULL;
