(MFC) Adding Attributes to an XML Node

Demonstrates how to add attributes to existing XML nodes.

The input XML is this:

<abc>
    <xyz>
        <mmm>123</mmm>
    </xyz>
</abc>

The output XML is this:

<abc a="123">
    <xyz b="456">
        <mmm c="789" d="000">123</mmm>
    </xyz>
</abc>

    success = xml.LoadXmlFile("add_attribute.xml");
    if (success != true) {

    }

    //  Add an attribute  a="123" to the root node:
    xml.AddAttribute("a","123");

    //  Navigate to the 1st child.  After calling FirstChild2,
    //  "xml" now references the node with the tag "xyz".
    xml.FirstChild2();
    xml.AddAttribute("b","456");

    //  Navigate to xyz's first child, which is the node having the
    //  tag "mmm".
    xml.FirstChild2();
    xml.AddAttribute("c","789");
    xml.AddAttribute("d","000");

    //  Revert back to the XML document root node
    xml.GetRoot2();

    //  Examine the result:
    strOut.append(xml.GetXml());
    strOut.append("\r\n");

    SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
