Sergiy Michka commented on XERCESC-1401:
----------------------------------------
I found what cause the undocumented exception.
To reproduce this in CreateDOMDocument xerces-c Sample project:
File: CreateDOMDocument.cpp, main
after this lines:
DOMText* catDataVal = doc->createTextNode(X("XML Parsing Tools"));
catElem->appendChild(catDataVal);
put this code:
catDataVal = 0;
try
{
catElem->appendChild(catDataVal);
}
catch (DOMException& rExc)
{
// #include <cassert>
//assert(&rExc); // normal documented exception: not catched
}
catch (...)
{
//assert(false); // not documented: catched
//access violation in the xercec binary, if the exception isnt handled
}
So the error was, that DOMNode::appendChild(DOMNode* pChild) throws an
exception, if pChild is null.
