currently I am implementing a solution to write individually created
XML data to a file using c++ and Xerces-c 2.7.0 library. Therefore I
am making use of DOMWriter class which allows me to write the
according DOM tree to a given location using LocalFileFormatTarget().
Everything works fine except that I cant define and set a certain XML
declaration. The tutorial seems to provide an easy way to do this by
applying the setEncoding(), setVersion() or setStandalone() functions
to the according DOMDocument. But even after setting those parameters
as well as enabling the fgDOMXMLDeclaration() feature of the DOMWriter
nothing is written except one empty line at the beginning of the
document. What am I doing wrong???
The according code snippet is given below:
const XMLCh gLS[] = { chLatin_L, chLatin_S, chNull };
DOMImplementation* impl =
DOMImplementationRegistry::getDOMImplementation(gL S);
DOMWriter* theSerializer = ((DOMImplementationLS*)impl)-
>createDOMWriter();if (theSerializer->canSetFeature(XMLUni::fgDOMXMLDeclaration,true) )
theSerializer->setFeature(XMLUni::fgDOMXMLDeclaration, true);
DOMDocument* doc;
doc = impl->createDocument(
0, // root element
namespaceURI.
XMLString::transcode("rootnode"),
// root element name
0); // document type
object(DTD).
doc->setEncoding(XMLString::transcode("UTF-8"));
doc->setVersion(XMLString::transcode("1.0"));
DOMNode* node = XMLwalker->getRoot(); //Set
Walker to Root node of the document
XMLFormatTarget *myFormTarget;
myFormTarget = new
LocalFileFormatTarget(written_XML_name.c_str()); //output to file
try{
theSerializer->writeNode(myFormTarget, *node);
}
catch.....
Any Help is appreciated as for my purposes the integration of the xml
declaration is compulsory!
