I was trying to add OpenCV XML file in the Qt resource file, but it's not working that's why I was given path of the file manually.

Can you please elaborate a little? Show some code? What _not working_ means? I'm pretty sure that you **can** make this work, but without further information it's just a too broad question. – Miki Feb 02 '16 at 12:07

When OpenCV reads a file, it will internally use the operating system's file open function fopen or similar, which cannot open QT resources https://stackoverflow.com/a/11155302/2079934. You should read the resource file with QFile and convert its contents to a std::string. Then, you can use OpenCV to parse the xml string https://stackoverflow.com/a/12729875/2079934.
