Hi Dave,
thanx for the hint, you are right - I am a bit unfamiliar with Unicode
strings... But if you have a handy link for getting an intro, I would
appreciate ;-)
I found a (fairly simple) way to get the desired char* out from XalanDOMString
by use of a simple function and the transcode() function as you suggested:
char* f( std::vector<char>& v )
{
char* pc = &v[0];
return pc;
};
std::vector<char> Sout = theResult->str().transcode();
char* x = f(Sout);
printf("\n...Evaluating the Result-Vector[0] x: %f\n", x);
Bye, Ingo

Hi Ingo,
Look at XalanDOMString::transcode() or the function
TranscodeToLocalCodePage().
Also, if you have a modern STL implementation on your platform, you may be
able to wcout instead of cout out, if you just want to display the string.

It may be difficult, if you're unfamiliar with Unicode strings, but not
impossible.
