该如何丝滑的把FAE给的一串Camera寄存器，转换成CamX的驱动代码

#include <iostream>
#include <fstream>

    regSettingToXML();

    cout << "End of Conversion." << endl;
    return 0;
}

void regSettingToXML(void)
{
    ofstream ofile;
    ofile.open(sensorNameXML);
    string xmlout;
    char str[16]{0};

    for(int i = 0; i < sizeof(regSetting)/sizeof(regSetting[0]); i += 2)
    {
        sprintf(str, "0x%X", regSetting[i]);
        xmlout += spaceNum + "<regSetting>\n" + spaceNum + " <registerAddr>" + static_cast<string>(str) + "</registerAddr>\n" + spaceNum;
