Hi, i've noticed the leak when running the following code:
while(true)
{
XMLTranscoder* utf8Transcoder;
XMLTransService::Codes failReason;
utf8Transcoder =
XMLPlatformUtils::fgTranscService->makeNewTranscoderFor("UTF-8", failReason,
16*1024);
size_t len = XMLString::stringLen(value);
XMLByte* utf8 = new XMLByte[(len*4)+1];
unsigned int eaten;
unsigned int utf8Len = utf8Transcoder->transcodeTo(my_hebrew_string, len,
utf8, len*4, eaten, XMLTranscoder::UnRep_Throw);
utf8[utf8Len] = '\0';
string str = (char*)utf8;
delete[] utf8;
You also need to release the transcoder
utf8Transcoder->release();
BTW, I would create it just once outside the 'while' loop.
As for the std::string -> XMLCh* conversion, just use the transcodeFrom
method exposed by the same transcoder.

}
Also, how can i accomplish the opposite task of convert an std::string to
XMLCh* without using the regular "transcode" function?
my string contains non-english characters and i need to convert it to an
XMLCh* ... how can i do that?
Thanks again

Hi,
I tried the code you posted, i only modified the line in which you create
the XMLByte*, instead of using "()" i replaced it with "[]". (when i used
the () and exception was thrown when i tried to delete the XMLByte*)
Yes, that was a typo, it should have been:
XMLByte* utf8 = new XMLByte[(len * 4) + 1];
The problem i've got now, is that this code causes a memory leak.. when i
tried to run it in a "while(true)" loop, it produced a serious leak. How
can
i fix it?
I have no idea why your code would be leaking. If you post a minimal
sample that exhibits the problem, perhaps someone can help you.
And another thing, is it ok to convert an XMLByte* to char*? or is there
a
better way for converting and XMLByte* to a std::string?
There's no problem with casting an XMLByte* to a char*. However, since
you're using a std::string as a return value, the best way to do this is
to
use a fixed size buffer for the transcode() call, then transcode and
append
each buffer to the result std::string in a loop. The parameters for each
call of transcode, and the return value will tell you how much of the
source string has been transcoded and how many bytes have been placed in
the output buffer.
