Hi 郭明,
transformation between xerces-internal string representation (XMLCh) and
local string representation (char) is done via XMLString::transcode(.).
XMLString::transcode returns a string (either XMLCh* or char*, depending
on the trancoding direction) that has to be released by the application
after use. The release method of choice is XMLString::release(.).
So, a typical scenario looks like this:
Given a const XMLCh *xml_string:
char *local_representation = XMLString::transcode(xml_string);
if (local_representation){
// use local_representation
XMLString::release(&local_representation);
}
You don't need to call any destructor explicitly.
BTW: which transcoder do you use for chinese transcoding: iconv or icu?
Cheers,
Axel
