Tinyxml修改xml文件、添加中文字符字段

1.修改xml文件:

bool write(char *file_path, std::vector &edit)
{
	//读取xml文件中的参数值
	TiXmlDocument* Document = new TiXmlDocument();
	if (!Document->LoadFile(FILE_PATH))
	{
		return false;
	}
	TiXmlElement* RootElement = Document->RootElement();		//根目录,这里是
 
	TiXmlElement* NextElement = RootElement->FirstChildElement();		//根目录下的第一个节点层 这里是
 
	if (NextElement->ValueTStr() == "Edits") {
		TiXmlElement* BoxElement = NextElement->FirstChildElement();//这里是str_num
		{
			int i = 0;
			while (BoxElement != NULL) {
				BoxElement->Clear();//将原有的文本删除
				TiXmlText*pValue = new TiXmlText(edit[i].c_str());//得到新的文本
				BoxElement->LinkEndChild(pValue);//更改文本
				Document->SaveFile(FILE_PATH);//保存文本
				i++;
				BoxElement = BoxElement->NextSiblingElement();
			}
		}
	}
	return true;
}

保存中文字符, 只需要将字符串转为utf-8的格式即可。

char* G2U(const char* gb2312)
{
	int len = MultiByteToWideChar(CP_ACP, 0, gb2312, -1, NULL, 0);
	wchar_t* wstr = new wchar_t[len + 1];
	memset(wstr, 0, len + 1);
	MultiByteToWideChar(CP_ACP, 0, gb2312, -1, wstr, len);
	len = WideCharToMultiByte(CP_UTF8, 0, wstr, -1, NULL, 0, NULL, NULL);
	char* str = new char[len + 1];
	memset(str, 0, len + 1);
	WideCharToMultiByte(CP_UTF8, 0, wstr, -1, str, len, NULL, NULL);
	if (wstr) delete[] wstr;
	return str;
}

完整的代码如下:

#include "stdafx.h"
#include"tinyxml.h"
#include"tinystr.h"
#include
#include
#include
#include 
 
#define FILE_PATH "F:\\visual studio 2015\\xml的读取和修改以及中文字符的存储\\test.xml"
 
bool read(char *file_path,std::vector &edit)
{
	//读取xml文件中的参数值
	TiXmlDocument* Document = new TiXmlDocument();
	if (!Document->LoadFile(FILE_PATH))
	{
		return false;
	}
	TiXmlElement* RootElement = Document->RootElement();		//根目录,这里是
 
	TiXmlElement* NextElement = RootElement->FirstChildElement();		//根目录下的第一个节点层 这里是
 
	if (NextElement->ValueTStr() == "Edits") {  
		TiXmlElement* BoxElement = NextElement->FirstChildElement();//这里是str_num
		{
			while (BoxElement != NULL) {
				edit.push_back(BoxElement->GetText());//获取BoxElement中的字符串
				BoxElement = BoxElement->NextSiblingElement();//获取BoxElement的下一个节点
			}
		}
	}
	return true;
}
 
char* G2U(const char* gb2312)
{
	int len = MultiByteToWideChar(CP_ACP, 0, gb2312, -1, NULL, 0);
	wchar_t* wstr = new wchar_t[len + 1];
	memset(wstr, 0, len + 1);
	MultiByteToWideChar(CP_ACP, 0, gb2312, -1, wstr, len);
	len = WideCharToMultiByte(CP_UTF8, 0, wstr, -1, NULL, 0, NULL, NULL);
	char* str = new char[len + 1];
	memset(str, 0, len + 1);
	WideCharToMultiByte(CP_UTF8, 0, wstr, -1, str, len, NULL, NULL);
	if (wstr) delete[] wstr;
	return str;
}
 
bool write(char *file_path, std::vector &edit)
{
	//读取xml文件中的参数值
	TiXmlDocument* Document = new TiXmlDocument();
	if (!Document->LoadFile(FILE_PATH))
	{
		return false;
	}
	TiXmlElement* RootElement = Document->RootElement();		//根目录,这里是
 
	TiXmlElement* NextElement = RootElement->FirstChildElement();		//根目录下的第一个节点层 这里是
 
	if (NextElement->ValueTStr() == "Edits") {
		TiXmlElement* BoxElement = NextElement->FirstChildElement();//这里是str_num
		{
			int i = 0;
			while (BoxElement != NULL) {
				BoxElement->Clear();//将原有的文本删除
				const char *a = edit[i].c_str();
				char *c = G2U(a);//为了保存中文字符需要将字符转为utf8
				TiXmlText*pValue = new TiXmlText(c);//得到新的文本
				BoxElement->LinkEndChild(pValue);//更改文本
				Document->SaveFile(FILE_PATH);//保存文本
				i++;
				BoxElement = BoxElement->NextSiblingElement();
			}
		}
	}
	return true;
}
 
int main()
{
	std::vector edit;
	bool c = read(FILE_PATH, edit);
	std::cout << edit.size() << std::endl;
	edit[0] = "301";
	edit[1] = "103";
	edit[2] = "正常";
	edit[3] = "%90";
	edit[4] = "NG";
	c = write(FILE_PATH, edit);
	std::cout << c << std::endl;
	system("pause");
    return 0;
}

得到的xml结果:



    
        301
        103
        正常
        %90
        NG
