Hi, Dave,
Thanks, I noticed that a dom element constructed by
DOM_Element() will compare == to 0 (similar to java's null
object reference variable), this is what I am looking for.
Regards,
Peiyong Zhang

Hi, Dave,
I've got a question for you, what shall i do in the 2nd return below?
thanks.
// Finds and returns the first child element node.
DOM_Element XUtil::getFirstChildElement(DOM_Node parent)
{
// search for node
DOM_Node child = parent.getFirstChild();
while (child != 0)
{
if (child.getNodeType() == DOM_Node::ELEMENT_NODE)
return static_cast<DOM_Element&>(child); /*** 1st return
***/
child = child.getNextSibling();
}
// not found
return ??? // 2nd return
}
Regards,
Peiyong Zhang
