RE: Casting DOM_Node to DOM_Element

[David_N_Bertoni]

How about:

   return DOM_Element();

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
