Strange problem

[Steve Brenneis]

I am having a problem with Xerces 2.8. I have the following code:

void ConfigReader::readConfig()
{
    ConfigErrorHandler err;

    try
    {
        xercesc::XercesDOMParser parser;
        parser.setValidationScheme(xercesc::XercesDOMParser::Val_Auto);
        parser.setErrorHandler(&err);
        parser.parse(configpath.c_str());
        doc = parser.getDocument();
        if (doc)
        {
            xercesc::DOMElement *root = doc->getDocumentElement();
        }
    }
    catch (const xercesc::XMLException& e)
    {
        StringHelper error(e.getMessage());
        throw ConfigException(std::string("Configuration error: ")
                        + std::string(error.toString()));
    }
}

The file it is reading looks like this:

<rahub>
  <general/>
</rahub>

When I call DOMDocument::getDocumentElement, it always returns null. There are 
no calls to any of the error or warning methods in  the error handler class and 
there are no exceptions thrown. I actually just copied and pasted this code 
from another application I wrote, which is working just fine.

Any ideas?
