AW: Reading german umlaute from xml file

[Freimann, Mario]

Dear David,

thanks for the hint. Switching to transcodeTo() and using ISO-8859-1, the 
transcoding works like a charme.

One question related to this. I want to write a xml document with the content

[[xml example]]

<?xml version="1.0" encoding="UTF-16" standalone="no" 
?><xtestroot><test>M&#252;nchen</test></xtestroot>

The code I use looks like the following:

[[code]]

        utf8Transcoder = 
XMLPlatformUtils::fgTransService->makeNewTranscoderFor("ISO-8859-1", 
failReason, 16*1024);
        DOMImplementation* _impl2 = 
DOMImplementationRegistry::getDOMImplementation(XMLString::transcode("LS"));
        DOMDocument* _doc2 = _impl2->createDocument(0, 
XMLString::transcode("xtestroot"), 0);
        DOMElement* _rootElem2 = _doc2->getDocumentElement();

        DOMElement* nextNode2 = 
_doc2->createElement(XMLString::transcode("test"));
        _rootElem2->appendChild(nextNode2);
        char* xData = "München";
        XMLCh* xOut = new XMLCh[ strlen(xData) * 6 + 1 ];
        int xRet = utf8Transcoder->transcodeFrom( (const XMLByte*)xData, 
strlen(xData), xOut, strlen(xData) * 6 + 1, eaten, charSizes );
        printf("debug xData [%s], eaten [%d], charSizes [%s], xRet [%d], xOut 
[%s]", xData, eaten, charSizes, xRet, xOut );
        DOMText* nodeData2 = _doc2->createTextNode( xOut );
        nextNode2->appendChild(nodeData2);

        DOMWriter* theSerializer2 = 
((DOMImplementationLS*)_impl2)->createDOMWriter();
        char* text2 = 
XMLString::transcode(theSerializer2->writeToString(*_doc2));
        printf(text2);
        printf("\n");
        XMLString::release(&text2);

The debugging printf shows that transcodeFrom() did its work. But 
unfortunately, printing the text2 variable doesn't give anything. I don't 
understand why the text isn't printed. Any help is appreciated.

[[output]]

debug xData [München], eaten [7], charSizes [], xRet [7], xOut [M]


With kind regards,

Mario Freimann

If you're trying to transcode from UTF-16, which is what you have, to UTF-8, 
you need to call "transcodeTo()" not "transcodeFrom()".
