/* First of all, thanks a lot for this great library. I spent too much time to learn this library and finally I got success.
// I couldn't find any material to learn this library but anyway I have done what I wanted to do.
//
// Now the only issue is with speed during importing X3D file.
// I don't understand why just 422 KB file takes too much to import/parse. I tried with several models, the famous one is dino.x3d (vertices = 2151, faces = 4300),
// It takes much time to parse approximate 1 minutes to parse. What I am not getting is, how can be xerces library too slow to parse XML file.
// I tried with debug lib, release lib, did everything, but still not getting the better results as I am getting with WRL files.
// There is no issue with WRL files, but when I try to import X3D files, parsing of x3d files take too long time, even my application gets stuck.
// Below is the source code from X3DParser.cpp file. I spent too much time to find this issue. The issue is with parser->parse(xmlFile); this line.
// I put cout<< in order to follow execution process, so finally what I find is, the execusion gets stuck at parser->parse(xmlFile); this line.
// Could you please tell me whats the issue with parsing of XML X3D files ? Why parsing of x3d is so slow ?
