读文件操作文件能容 和 String 之间转化

读XML,头文件#include <fstream>

	
	string out_fileData;

	std::ifstream inFile("example3.xml");
	if (!inFile)
	{
		out_fileData = std::string("");
	}

	while (inFile.good())   
	{
		out_fileData += inFile.get();		
	}

	inFile.close();

	cout<<out_fileData<<endl;

写文件

	string fileData = "<?xml version=\"1.0\" encoding=\"UTF-8\" ?>\n<test name1=\"kevin1\" name2=\"kevin2\" name3=\"kevin3\" />";
	std::ofstream* ofstream = new std::ofstream();
	ofstream->open("example4.xml");
	if (!(*ofstream))
	{
		//std::cout << "Error: Cannot open file: " << m_fullFileName << std::endl;
	}
	else
	{
		*ofstream << fileData << "\r\n\r\n";
		ofstream->flush();
	}
	return 0;

创建的文件格式内容为：

<?xml version="1.0" encoding="UTF-8" ?>
<test name1="kevin1" name2="kevin2" name3="kevin3" />
