This will work but will be roughly O(N^2) rather than O(N) because the
native data structure for DOM is a linked list of children.
So it is _much_ better to use something like:
Element newParent = doc1.getElementById("group1")
Node current = doc2Elements.getFirstChild();
while (current != NULL) {
Node copyNode = doc1.importNode(current, true);
newParent.appendChild(copyNode);
}
I'll also point out that doc1.getElementById("group1") would be best pulled
out of the loop.
