What you are trying to do is very bad practice. if the GetText()
member function is mandating that the returned character array not
have its contents changed, then you should honor that.
If you really want to strip the const-ness (even though you
shouldn't), then you do a const_cast<>() on the right side of the
expression to strip the const rather than trying to cast the left
side to be const.

The following code produces a warning from GCC about "target of

char *typeOfQ = NULL;
static_cast<const char *>(typeOfQ) =
handle.FirstChildElement("fieldlabel").Element()->NextSiblingElement
("fieldentry")->GetText();
