Hi Leon,

Since you say that you don't know what argc is, I'm going to give you 
very basic advice. Don't be offended. :-)

When you run your program, you need to do it like this:
myProgramName myXmlFileName

It should not matter what you have named the XML file. If it is in a 
directory different from the one where the program lives, you should 
probably specify the full path.

From your description of your problem, it sounds like you aren't 
passing the XML file name as a command line parameter.

P.S. argc contains the number of command line arguments, while argv is 
an array of strings that contain each of the command line parameters. 
You always get the name of the program you're running in argv[0], so 
argc is always at least one, but the program expects to see another 
argument.
