Err, this is C++, right? This should work:
DOM_Node tmp_node = messageNodes.item(i);
DOM_Element messageElement = static_cast<DOM_Element&>(tmp_node);
I've tried this without using the tmp_node step (i.e. just a static_cast
on the return value from item()) but the compiler barfed on it. I ended
up creating a function to do this because it was happening so much, i.e.
DOM_Element getFromNodeList(DOM_NodeList& n, unsigned int which)
{
DOM_Node tmp_node = n.item(which);
DOM_Element result = static_cast<DOM_Element&>(tmp_node);
return result;
}
And then I trust the compiler to inline and optimise this function
appropriately. If it's not performance critical this approach will
definitely work, but someone else may have a better solution.
Best regards,
Mike.
