Deep Clone:  I see there is an 'XMLNode::ShallowClone(doc)'.
Am I missing something? I will write a 'DeepClone() and post it here, but do I need to write that? I would think it'd be somewhere. Thanks!

// DeepClone All children of 'nodeSrc' into 'newNode', using document 'DocDest', and nodeSrc's parent is 'parent'.
// Nice recursive function. Code by: Todd A. Marshall
void CMyClass::DeepClone(tinyxml2::XMLNode *newNode,tinyxml2::XMLNode *nodeSrc,tinyxml2::XMLDocument *DocDest,tinyxml2::XMLNode *parent)
{
tinyxml2::XMLNode *child = nodeSrc->FirstChild(); // Start at first child
tinyxml2::XMLNode *newNode2;
if (child)
{
newNode2 = child->ShallowClone(DocDest); // Copy child to newNode2
DeepClone(newNode2,child,DocDest,nodeSrc); // Deep clone the child into newNode2 children
newNode->InsertFirstChild(newNode2); // Insert the child created (newNode2)
}
else return; // NO CHILDREN: no first child, done.
tinyxml2::XMLNode *child2; // Next source child cloned
tinyxml2::XMLNode *lastClone = newNode2; // last child created
while (1) // deep clone children 2..n
{
child2 = child->NextSibling();
if (!child2)
break;
tinyxml2::XMLNode *newNode2 = child2->ShallowClone(DocDest); // Copy child
DeepClone(newNode2,child2,DocDest,nodeSrc); // Deep clone the child
newNode->InsertAfterChild(lastClone,newNode2);
child = child2;
lastClone = newNode2;
}
}

Nice code!

A couple of constants could be added here:

void DeepClone(tinyxml2::XMLNode*, const tinyxml2::XMLNode*, tinyxml2::XMLDocument*, const tinyxml2::XMLNode*);

Also, I agree with you that deep clone should be included in tinyxml2.

XMLNode *deepCopy( XMLNode *src, XMLDocument *destDoc )
{
    XMLNode *current = src->ShallowClone( destDoc );
    for( XMLNode *child=src->FirstChild(); child; child=child->NextSibling() )
    {
        current->InsertEndChild( deepCopy( child, destDoc ) );
    }

    return current;
}
