GDML parser has a parser.GetVariable() function, which is good. However, there appears no way to check if a variable name has been defined before calling the function, so either it works or it core dumps, depending on what the user has put in the geometry file. I was hoping there would be a parser.IsValid() function to handle this gracefully, but I have not found it. Or, is there some other way?
