Demonstrates how to remove an XML subtree from an XML document. Unicode C++

    // The XML file we're loading contains this:

    // <?xml version="1.0" encoding="iso-8859-2" ?>

    // Navigate to the node that is the root of the subtree to be deleted.
    // In this case, we wish to find the node having tag "ROW" with content "477956"

    // Examine the xml2, it should be just the subtree.

    // Now detach xml2 from the it's XML document.
    // xml2 will now be it's own XML document.
    xml2->RemoveFromTree();

    // Examine our original XML document.  The subtree is removed:
    wprintf(L"%s\n",xml.getXml());
