Hi Michael,
I use to take 'static_cast' in order to obtain a DOMElement-pointer from
a DOMNode-pointer. But usually I check the type of the node actually to
be DOMNode::ELEMENT_NODE before performing the cast.
static_cast is a weaker concept than dynamic_cast, sure. However,
static_cast is a stronger concept than reinterpret_cast, since the
compiler can check if there is a descent relationship between the
types.
BTW: do there exist any C++-compilers which do not understand
static_cast?
Cheers,
Axel
