Hi Jordan, I'm not available to the list Mon-Thur and I'm catching up. I
didn't see anyone respond to this so I will give it a shot. I have noticed
that if the filename given to the parser to parse is invalid, that the
parser neither calls an error handler or throws an exception. It simply
instantiates an empty document of which the first element is basically NULL.
Hence, the following three lines will work.
parser->parse(xmlFile);
DOM_Document doc = parser->getDocument(); //
Empty document
DOM_Element root = doc.getDocumentElement(); //
first element of an empty document contains an internal NULL 'fImpl'.
'root' ends up having an internal 'fImpl' member of NULL. The
'getElementsByTagName()' call tries to access this NULL 'fImpl' pointer and
hence, blows up. So one suggestion I can offer up is to verify your
'xmlFile' path to the DOMParser::parse(xmlFile') routine.
