Hi There,
use XMLString::transcode(localname) which will a pointer to a character
array.
Thanks

Subject: RE: Newbie Problems with Simple SAXParser
When i get an event that an element was found, i take the localname in my
startElement method and try to put it in a char array, like (don`t laugh,
i`m new to c++!):
int f = XERCES_CPP_NAMESPACE::XMLString::stringLen(localname);
char *element = (char *)malloc ( f * sizeof(char));
for (int i = 0; i < f;i++)
{
element[i] = (char) localname [i];
}
std::cout << "Found element..." << element << "\n";
free(element);
When i run my application i get the name of my element, but there are
padding characters behind the actually elementname. Is that due to a
different encoding? (XMLCh*?) Is there a method i have to call, which
creates a string from the localname?
Thanks
