Re: WG: cast Problem: from XalanDOMString to char* ???

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.
