I have the same problem, I am using XSLT on an enveloped Signature Transform.
In my case the dsig namespace is inserted into the resulting data and passed to
the hash function.
for a quick fix/test I've inserted a test-function and replaced the c14n
test-function: converts DOMNode to safeBuffer
safeBuffer test(xercesc::DOMNode *node)
{
DOMImplementationLS* impl =
DOMImplementationRegistry::getDOMImplementation(L"LS");
DOMWriter* wrt = impl->createDOMWriter();
MemBufFormatTarget* target = new MemBufFormatTarget();
wrt->writeNode(target,*node);
char* t = new char[target->getLen()+1];
memset(t,'\0',target->getLen()+1);
memcpy(t,target->getRawBuffer(),target->getLen());
safeBuffer ret = t;
delete[] t;
wrt->release();
delete target;
return ret;
}
and changes in DSIGTransformXSL::appendTransformer
// Create the XSLT transform
XSECnew(x, TXFMXSL(mp_txfmNode->getOwnerDocument()));
input->appendTxfm(x);
/*
// Again use C14n (convenient) to translate to a SafeBuffer
XSECC14n20010315 c14n(mp_txfmNode->getOwnerDocument(), mp_stylesheetNode);
safeBuffer sbStyleSheet;
unsigned int size, count;
unsigned char buf[512];
size = 0;
while ((count = c14n.outputBuffer(buf, 512)) != 0) {
sbStyleSheet.sbMemcpyIn(size, buf, count);
size += count;
}
sbStyleSheet[size] = '\0'; // Terminate as though a string
*/
safeBuffer sbStyleSheet = test(mp_stylesheetNode);
I will build an XSECDomToSafeBuffer class with the same syntax as
XSECC14n20010315, so there should only be small changes except the class :)
Coming in the next few days...
