if you want only data of .xsd file then you could save as this file as .txt and then read file as normal text file,

but reading direct .xsd file may not allows by microsoft.

The .xsd file is a text file and can be read directly by C++

1 solution

I think that there are two options. The first is to open the file in text mode and then read a line at a time, appending each line to your string:

C++
std::string result;
std::ifstream file("myfile.xsd");
if(file.is_open())
{
  while(file.good())
  {
    std::string temp;
    std::getline(file, temp);
    result.append(temp);
  }
  file.close();
}


The second way is to treat it as a binary file, read it into memory and then assign to a string. This method may be more efficient if your file is large or has a lot of lines.

C++
std::string result;
char* memblock;
std::ifstream file("myfile.xsd", std::ios::in|std::ios::binary|std::ios::ate);
if (file.is_open())
{
  std::ifstream::pos_type size = file.tellg();
  memblock = new char[size];
  file.seekg(0, std::ios::beg);
  file.read(memblock, size);
  file.close();
  result.assign(memblock, size);
  delete[] memblock;
}

getting error for this line
std::ifstream file("myfile.xsd", std::ios::in|std::ios::binary|std::ios::ate);

A compile error or run-time error? What is the error?

You need to include both of the following include files:

#include <iostream>
#include <fstream>
