About DOMString.transcode()

Hi, I come here again for help, thanks a lot.

I am now processing XML data with the SJIS encoding. I didn't use icu. The
way I tried is changing the encoding model previously. The function is as
the following:

SJIStoUTF8( char *inSJIS, int strlen(inSJIS), char *outUTF8);
UTF8toSJIS(char *inUTF8, char *outSJIS)

When running with the functions separately, i.e. first change japanese to
UTF8, then change UTF8 back to SJIS, the returned japanese is showed
correctly.(The main src functions I used inside them are:
MultiByteToWideChar() & WideCharToMultiByte()).

So,  I parsed the XML data this way:
1. Changed the text from SJIS --> UTF8
2. Write the UTF8 text as a DOM_Text and inserted in the XML data.
3. Parse the XML data.

Till here, there is no problem. Suppose the completed XML data is as the
following:
  <elemTag>UTF8txt</elemTag>

But when I want to change the DOMString type data to char type(using
transcode()) to let it be input into UTF8toSJIS(), there's nothing returned.
So I tried printing out the text data this way:
    cout << elemTag.getFirstChild().getNodeValue().transcode() << endl;

there's nothing appeared. If I just test with "ABCD" instead of japanese,
the result is perfectly good. It seems DOMString.transcode() cannot
recognize those UTF8 text so just ignored them and returned nothing back.

What I can do to solve this problem? Why should DOMString.transcode()
ignored those UTF8 encoding texts?

Thanks a lot,

If you want to transcode to something besides the LCP, then create an XMLTranscoder object. Use the transcoder object in the XMLPlatformUtils to create a transcoder for the encoding that you want, and use that object to do your transcoding.

  To state my problem in another way, that is:
  The API document for " char *DOMString::transcode()" say that it returns a copy of the string, transcoded to the local code page. What I want is just to transfer the DOMString object to a string of 8-bit Windows(ANSI) characters, not to the local code page. It should be made possible for Xerces, isn't it?

  Any hint will be helpful, thanks a lot,
