Ok, the simple XMLString::transcode does not work
for me, so I tried with a Trancoder.
Please look at this class:
class XStr3
{
private :
XMLCh* fUnicodeForm;
XMLTranscoder* tc;
public :
//
-----------------------------------------------------------------------
// Constructors and Destructor
//
-----------------------------------------------------------------------
XStr3(XMLTranscoder* ttc, const char* const
toTranscode)
{
tc = ttc;
unsigned int bytesEaten;
unsigned int srcCount = strlen(toTranscode);
unsigned int maxChars = 1024;
unsigned char *cs = new unsigned char[1024];
memset(cs, 0, 1024);
fUnicodeForm = new XMLCh[1024];
memset(fUnicodeForm, 0, 1024);
tc->transcodeFrom((const XMLByte*)
toTranscode, srcCount, fUnicodeForm, maxChars,
bytesEaten, cs);
char *pMsg =
XMLString::transcode(fUnicodeForm);
cout << "retranscoded string:" << pMsg <<
endl;
delete [] pMsg;
XMLByte dest[1024];
unsigned int charsEaten;
tc->transcodeTo(fUnicodeForm, 1024, dest,
1024, charsEaten, XMLTranscoder::UnRep_Throw);
cout << "retranscoded string, second try:" <<
(char*)dest << endl;
}
~XStr3()
{
delete [] fUnicodeForm;
}
const XMLCh* unicodeForm() const
{
return fUnicodeForm;
}
};
#define X3(ttc, str) XStr3(ttc, str).unicodeForm()
Before I build the DOMDocument I build the
Transcoder
XMLTransService::Codes ok;
XMLTranscoder* tc =
XMLPlatformUtils::fgTransService->makeNewTranscoderFor("ISO-8859-1",
ok, 1024);
Then I build the DOMDocument (see sample
CreateDomDocument) but instead of
DOMText* devByDataVal =
doc->createTextNode(X("Apache Software
Foundation"));
is use now
DOMText* devByDataVal =
doc->createTextNode(X3(tc, "�tsch"));
..........
The output is:
retranscoded string:
retranscoded string, second try:�tsch
<?xml version="1.0" encoding="ISO-8859-1"
standalone="no"
?><company><product>Xerces-C</product><category
idea="great">XML Parsing
Toolsa</category><developedBy></developedBy></company>
.............
I still do not understand:
1) Why the simple transcode method does not work?
(see retranscoded string is empty)
2) Why is <developedBy></developedBy> empty again
? I expected the "�tsch".
Any help is very appreciate,
best regards
