Hi,
Im sorry, I must be missing something. I dont understand why you
just cant clone the whole DOMDocument and then make your alterations to
the newly cloned one.
ie.
DOMDocument *doc = parser->getDocument();
DOMDocument *newDoc = (DOMDocument *)doc->cloneNode(doc);
//make some alterations to the newDoc
XMLCh tempStr[100];
XMLString::transcode("LS", tempStr, 99);
DOMImplementation *impl =
DOMImplementationRegistry::getDOMImplementation(tempStr);
DOMWriter *theSerializer =
((DOMImplementationLS*)impl)->createDOMWriter();
XMLFormatTarget *myFormTarget = new StdOutFormatTarget();
theSerializer->writeNode(myFormTarget, *newDoc);
if you really cant do this then you can just import the comment into the
new doc afterwards. Obviously you could do it better than the following
piece of code :)
DOMDocument *doc = parser->getDocument();
DOMImplementation* impl =
DOMImplementationRegistry::getDOMImplementation(XMLString::transcode("Core"));
DOMDocument* newDoc = impl->createDocument();
//this is the original comment
DOMNode *com = doc->getFirstChild();
//tis is the imported comment
DOMNode *icom = newDoc->importNode(com, true);
newDoc->appendChild(newDoc->importNode(doc->getDocumentElement(),
true));
//now we insert the comment as a sibling of the doc ele
newDoc->insertBefore(icom, newDoc->getDocumentElement());
XMLCh tempStr[100];
XMLString::transcode("LS", tempStr, 99);
DOMImplementation *impl2 =
DOMImplementationRegistry::getDOMImplementation(tempStr);
DOMWriter *theSerializer =
((DOMImplementationLS*)impl2)->createDOMWriter();
XMLFormatTarget *myFormTarget = new StdOutFormatTarget();
theSerializer->writeNode(myFormTarget, *newDoc);
delete theSerializer;
