    // When the autoCreate argument equals true, the UpdateAttrAt
    // method auto-creates the children as needed:

    xml.UpdateAttrAt("mammal|rodent|squirrel",autoCreate,"feature","bushy tail");
    xml.UpdateAttrAt("mammal|rodent|rat",autoCreate,"feature","long hairless tail");

    // Show the XML
    strOut.append(xml.getXml());
